Contract cancellation

On the 29th of August 2015,I forwarded a contract cancellation to Telkom.This is after I tried to have my contract upgraded 5 times through various platforms available at Telkom. On the 03rd and the 06th of September,I sent emails to the cancellations department requesting for an acknowledgement of my email to cancel the contract and no response was received from Telkom.On the 09th of September,I contacted Telkom telephonically to register the cancellation log and was given a reference number (***4), and was told someone would contact me in 2 days to discuss my cancellation. A Telkom representative contacted me on the 16th of September (7 days later) and I relayed my frustration to her with regards to the upgrade and why I had opted to cancel my contract .She promised to arrange for an upgrade for me and she got back to me in 5 minutes as promised and asked for my address and the package plus handset I was interested in.She later confirmed that she had found my handset and I would be contacted for a delivery. I contacted Telkom on the 23rd,28th,29th and the 30th of September and no one has contacted me to date.I have decided to port my number to another service provider.
