After signing a contract they don't give a damn

I have been a client of Altech Autopage for almost 20 years. For the first time, I have had atrocious service. On 18 March I phoned them requesting an upgrade which they assured me would be dispatched within a week. 2 weeks later I phoned them back and they confirmed that they had no instruction or record of my call. A phone was eventually delivered to me approximately one month after my initial request. The contract required me to phone Autopage and request a migration from Vodacom to MTN. I made 5 calls over a 2 week period with no result. So, after 2 months I have a phone that doesn't work. I have left a message for Zaheer Vallee (Manager: Upgrade Dept) 3 times already but he fails to return my calls. I have also discovered that, should you wish to transfer data from your old phone to your new phone you need to use a larger cellphone provider, at extra cost, as Autopage is too small to provide such a service to customers. According to the Consumer Protection Act I am well within my rights to cancel this contract as the phone I have is not connected to any network and therefore cannot be used. DO YOURSELF A FAVOUR: DO NOT USE AUTOPAGE.
