Poor customer service and *******s

I had a contract with telkom and in July I was due for an upgrade, I did the upgrade and got the phone but later realized that I didn't like the phone - I then called to arrange for the phone to be collected and that was still within the cooling off period,I kept on calling and sending emails until eventually after 2 weeks the phone was collected, I then went to a store to have the contract cancelled.

To my surprise in August I got billed for the phone that was not in my possession, so I got charged for services I didn't use. After countless calls and emails trying to have this resolved and get refunded it was still not resolved- when ever I called different agents kept on advising me that they have logged tickets and escalated the query until I decided to reverse the debited amount as I wasn't willing to pay for services that were of no use to me. And again this month R2200 got debited from my bank account- 3 months later this still has not been resolved.

This is so frustrating as they now took the last money I had in my account for a phone they took back.I have again called and as usual a ticket has been logged, why am I being treated like this? After being a loyal customer to Telkom for 2 years.

Can I have this resolved asap please.
