Incorrect Charges

First of all to start off my issue I has a previous contract for 2x Huawei P9 Lite devices. In July 2019 I chose to upgrade my account early for one of the devices, the second devices contract I decided to cancel. This did not happen and I was incorrectly charged for until December 2019. The contract was only correctly canceled after 2 months of fighting and multiple trips into the Cresta store.

I was told that a credit would then be due to me as I had been paying for the contract incorrectly for 5 months. This never happened.

My current issue with my contract is that I have now had my services suspended for 2 months and within the last 2 weeks I have had a total of R 2052.48 (one amount of R1 026.24 taken on the 20th and second amount of R1 026.24 taken on the 31st) I have yet to have my services reconnected and I still have not seen any correction to my invoice. My current invoice is still incorrect and hasn't reflected the funds taken from my account. I have been on hold waiting to talk to an agent for over 45 minutes now to find some clarity on my issue.
