NOT GETTING WHAT WAS DISCUSSED NO RESPONSE

On the 11th or 12th May I called Altech Autopage Cellular for an upgrade and the following package was negotiated. I would get 100 sms, 100 anytime minutes and 200 MB data at a cost of R314.00 p.m. At the end of June I get an account for over R650.00. This is when the endless telephone calls to Vishen in the retentions dept. started. To cut a very long story and endless telephone calls to both call centre and retentions dept. short, I am still no closer to get this issue resolved. On the 23rd June I again spoke to Vishen and advised that I want to cancel this contract as I am not getting what we negotiated. Vishen escalated this call to his manager, Vahir Vally a week a go, and to date I am still waiting for her to call me. I called again this morning, received another reference no. and still, no response from Vahir. I have left numerous messages on her phone. I have been a loyal Altech Autopage customer for more than 10 years, and this is the first time that I have ever logged a complaint and I am getting this type of treatment. I am not happy, I want this issue resolved.
