7 months later still no action but promises

My cancellation of my Mobile contract ( I wanted to renew to a different contract) could not be processed because according to their records...my 2 year contract will run from 20 March 2013- august 2016! This is because their Mobile office in Shelly beach admits it was their mistake to upgrade the 'Unlimited data Offer' INSTEAD OF REGISTERING IT ONLY! They acknowledge that my account was the first that they had done and had not had clear instructions on how to apply this! This meant that I now have an UNLIMITED' Contract at R1700 per month extending for 3 1/2 years! Besides the fact the the Problematic Z10 contract payment is only for 2 years...no credit has even been passed for the extended phone payment!! <br> I am forced to have my accounts (I have 2 phones with Telkom) run one month in arrears...however...where they to suspend services...then accounts department cannot process the query until arrears are up to date! <br> I tried from April 2015 to renew this with a new contract and was told it is to new to renew this contract!!<br> I have spent hours on the phones to Telkom Mobile members...all assure me..yes sir we understand .<br> This cannot go on. I am due a 8500 min credit!<br>
