CONTRACT ***** AND SHADY "NEW DEAL"

On December 12th 2017, I have signed a deal with Vodacom on a Macbook Air and a 5GB data promo bundle. The duration of the contract was 36 months. This means that the contract is due to expire in December 2020. When I opened my online profile today, the contract terms have changed to Upgrade due in DECEMBER 2020 and the end date of the contract is set to May 2021. WHERE DO THE EXTRA 6 MONTHS COME FROM?!

Struggling to get hold of representatives, I have given up and contacted the Key West branch where I have received a reference number. I have explained the situation to the consultant (she was very helpful). The consultant then mentioned that the reason for the new dates on the contract was that there was a brief time where the contract was not paid. I agree to this as I was jobless at the time and I did let them know. She went on to explain that what they have done was to close the contract. I let the consultant know that I did pay the arrears and the contract just continued. The lady responded that when Vodacom received the arrears amount, they did not continue with the contract - THEY OPENED A NEW DEAL!!!

So here is my question. How does Vodacom open a new deal without my consent? Where did I sign for the new deal? They did not even communicate this to me. This is ********, ********* and plain *****!

Here is my reference number: ***

Vodacom needs to get back to me before the end of the month. As it stands now, the contract is not enforceable by law and should be terminated with immediate effect!

Vodacom, how do you just "sign" deals on behalf of your clients? Please prove to me where I have signed this "new deal" and prove to me what new product you offered me under this "new deal". The contract that I have was signed and dated on December 12 2017 for 36 months.

This needs to be resolved NOW.
