Bad Service from Mobile Talk

i am having endless problems trying to get hold of anyone at this company. If you call their customer care line number , you are kept on hold forever and a day. I called on Friday to lodge a complaint and i had to deal with a very rude agent over the phone . I was forced to drop the call as he refused to put me through to a manager to discuss the merits of my complaint. I was forced to send an e-mail on Friday at 16h31 and i received a reference number. To date nobody has done anything about this complaint. I had to send an e-mail on Saturday and Sunday and to date nobody has had the common decency to call me or contact me via e-mail. I have been battling to call them for the whole morning . The main complaint is that I was not informed about the 48 hours and 72 hours wait for the sim card to be activated. I also did not ask for an extra 1GB to be debited at R40.00 - this they just put on my account without my consent . {this has since been cancelled when I called an agent this morning. On Friday when I lodged the complaint , i was told categorially that there would be a cancellation fee and this fee would be sent to me on Monday morning by the back of office team . When i asked what they amount would be, this rude agent refused to give me an answer. i requested to speak to a manger and he refused and I was forced to drop the call due to his shocking behavior. Yet this morning i spoke to a different agent that handled the complaint in a complete different manner and advised me that there would be NO CHARGES !!!! as I was in the cooling off period. Please note that only received the package on Friday afternoon and I lodged a complaint the same day. This new agent will be sending a courier company to collect the package and then this whole order will be cancelled as per my request . I find their service to be totally unacceptable and very unprofessional and nobody cares about the customer at the end of the day. It has been an uphill battle to resolve my issue.
