telemarketing company yes they call for vodafone and they get reps in to draw the business up a bill comparison. I got them in thought it couldnt hurt and now im saving up to $4000 p/month for the business. Very worth while to listen to what they have to say and get them in to the business. It only takes about 10 mintues too

This is a telemarketing compnay that calls on behalf of many companies(including Vodaphone and optus) to try and get your business. Only recently they have made it so that you can call back in on the number that calls you. The opertators can't pick up as this is a call centre set-up, however the operator gets a beeping (call waiting tone) as they are on other calls. They are located at upstairs 841 north east road Valley View 5093phone 1300 764 505Hope you enjoy this insight

very simple to deal with telemarketers.Choose a name no-one in your office has (our non-existant purchasing officer is Jack Shyte),When telemarketers ask who they need to speak to tell them 'jack, but he does not come in until after 7pm.Within a 2 weeks every telemarketing who calls will be asking specifically for the non existant 'jack shyte'.You now know instantly (no matter what excuse they make up) that it is just anohter telemarketer.Surprising how many times i am told that jack shyte had a meeting with them a few months ago and they are only waiting on a copy of our current bill to finish off HIS 'order'.My only response is 'sorry i dont know jack shyte he must work in (non existant) purchases department they can be contacted on (08) 8465 4300 *G*

I keep getting calls form this location no Dial tone at other end
