Nightmare contract at telkom and *********** staff

I took a Telkom contract in the middle of August this year, to my disappointment, the porting of my old cell number to my new contracted number a few days later was such a complicated issue that the Telkom staff member could not figure it out and messed up my contract. My contract was cancelled thereafter mirrored onto a prepaid Telkom number wrongfully and I end up having 2 billing arrangements. I was debited twice, on the 25/09/2018 and on the 01/10/2018. when I queried this at the Musgrave branch as this is the branch my contract was taken, I was told to call the call centre which is of no help at all! I went to the store for the 3rd time for help after explaining myself numerous times, I was told that it was a big mess and it will get sorted out, to date I have not received my money or any feedback. the call centre logged a case to return the funds to me-this was done on the 01/10/2018 and I was advised that it would take 72 hours however I still have not received a call from them. I ever regret taking this contract as it makes my life all the more difficult with *********** people to deal with. I would appreciate my funds (R 521.18) returned to me and a letter stating that this would not happen again.
