Billed for contract that was not active yet.

Hi<br> <br> I app**** for a S4 mini in December and Telkom Mobile at Bayside Mall never had stock. In January I returned to the store to enquire if the device has arrived. I was very upset that the device was not there yet and nobody informed me or kept me updated. I left the store and went to another branch where I was helped and I choose a S5 mini instead. When the consultant wanted to process the transaction, they said that the contract has been cancelled and a new one had to be app**** for. She app**** for the new one and a few days later I received a bill of R3400 for the cancellation of previous contract. I did not even receive a device and never port cell no. How can Telkom Mobile make such a big mistake. I called their helpdesk numerous times and nobody can help me resolve this matter. I changed networks from Vodacom to Telkom Mobile and I am starting to regret it.
