I was told these people were from bigpond and same thing as everyone else my computer was infected. Do not believe these people

I received a call from (02) 8014 7459 last week informing me that I had been sent many updates that had not been actioned on my computer, and as my computer had been in storage for 12 months due to shifting house I thought the call was legitimate. The person I first spoke to said his name was" Andrew Wayne" the technical supervisor, he had an Indian accent, I questioned him on how he got my details, especially my phone number as it had only been connected to my new address the week before this call, I even said to him that how do I know this isn't a scam to which he replied, oh no madame we are from "Techforhelp" which is connected to all computer users and that all I needed to do was turn on my computer and I could watch everything they would be doing, they were able to answer every question I asked, so thinking that they were correct about all the updates being not actioned I turned on my computer. After 91 minutes of watching things on my screen being done and clicking on ok every now and then he told me that I would have to pay $389 to which I told them I could not afford as I am a senior citizen, he then said in that case it would be just $199 and then said he would speak to his supervisor who came to the phone he was also Indian and gave the name "Ron Williams" he told me that everyone with these computer problems needed to pay. He said that I could pay it in instalments, 1st payment $39.99 2nd payment $69.99 and finaI payment $99.99. I did pay the $39.99 and even received a call the next day, fortunately I was not home but he left a message asking how my computer was running and if I needed any further information to call him on the above number, I still have that message on my answering machine.
I'm now worried that I may have compromised my bank details and emails, What should I do?

Hi Brad I am afraid that I am one of the people who did get scamed. I read your message and it happened to me in the exact same way as you discribe although I did let them remotly take over my computer. They sen me a form to fill out asking me to pay $299 Au $. I told them that I would not pay because I wanted to speak to someone who knew about computers. When I told him this he got angry but I insisted that I was not going to pay. Finaly he said OK and he would ring back tomorrow.
My question is do you think that they have put some type of Spy Ware on my computer or something else?
I have stoped using my desktop computer and am using me laptop at the moment.
Can eney one help?
Thanks

Hi,  I just had this caller who gave me the name Tech 12 Home and the tel no.  Indian origin, could hardly understand the caller.  He assured me there was no selling involved and asked me to check event viewer and discussed the error/warnings.

They told me they were working closely with Microsoft and are the only tech support company working in collaboration with Microsoft to offer the service.  They wouldn't tell me how they knoew what was on my PC just said they'd sent numerous warnings to me??

My parents just had a call from this number today, similar call, late at night claiming to be from a company but his english so bad it was unclear which and wanted access to the computer to "fix" things.

Why don't we ring them and offer to fix, sell, advertise, hound, scam and blog them until there ears bleed, just a thought.

Caller just called me, his name was Austin, he said he was calling from Microsoft Windows tech support!!! So they are trying different names, He said that people in my area have reported an update problem which is affecting how the computer runs, I got a phone no. to call them back as I was busy at the time, first I wanted to find out why Microsoft was calling me because it seemed suspicious, so I got the no. and ended the call. The company answers as Tech For Help, the no. is: (02) 8014 7459
