After receiving several calls where I answered and there was nobody there, I called the number (8988-5338) and spoke to an operator. I gave them my number and they were able to tell me who was calling. They were calling on behalf of GIO to offer new products. They were also able to take me off the list.

These calls have been plaguing me since mid April. Some of them hang up when you answer the phone. I made an application to the "do not call register list" do you think it worked... hell no! I then called my provider "3" they advised I had given consent to be on a "marketing list" and de-activated this.
I have no idea what they were talking about as I have never responded to strange text messages etc... can't say the girl on the other end was too helpful but that would be asking too much since the "3" call centre is located in Calcutta! needless to say, I haven't beem bothered by these calls since, so I suggest you contact your provider if you want these calls to cease.

I got calls from this number almost everyday. so annoying!

How can we stop this?? Please help.

I am still receiving calls from this number, but it only seems to occur when my phone is on roaming overseas.They asked me about a credit card I had recently taken out with HSBC - the scaring thing is I actually had taken one out - so they must be stealing the numbers from somewhere.

If you have a few minutes spare, why not have some fun at the callers expense?

Go to http://www.xs4all.nl/~egbg/counterscript.html, print the script (pdf version is better) and keep it by your phone for future annoying calls.

Good Luck

Same here. Up to about 7 or 8 calls from (02) 8988 5398, (02) 8988 7183 or (02) 8198 6598. Never leave a message and I never answer. All a bit sus.
