A sad and dull Christmas due to Telkoms mistake

I had a 24 months contract with Telkom 5/6 years ago which I was paying for up until contract ended. Unfortunately a short while after I had lost my cell phone and never replaced the Telkom sim but decided to take a new contract. This is now 5+ years later with no contact of any form from Telkom all these years to my surprise my bank account is debited (Debi-check) a sum of R1250 in November without my approval so I called in to query was told I am owing because " I was supposed to cancel" yet I haven't been using the account and more importantly I was not told initially that after contract ends I must cancel. What's even more frustrating is that I did voice this to all the consultants I've spoken to thus far in their call center and non of them have been able to assist and seeing that I didn't get any joy I requested the call to be escalated but no one has ever called me since!.

The last consultant I spoke to in November advised me that I was supposed to read the T's and C's and advised me that I cannot be refunded but he will cancel the contract and the balance will be written off, but now in December 20 again an amount in excess of R3000 was debited and when I called in to request a refund simingly no one is able to assist me and I am told to wait 14 days even though account reflects it is canceled.

Can someone please call me or help as I really don't know what to do now I couldn't even get my kids a Christmas gift as this money was all I had and Telkom took it from me just like that.
