unprofessional mobile contracts @ telkom mobile

On the 22/01/2014 I took a contract on the 1/09/2014 my contract got into arrears reason being Telkom debit order was to debit last day of the month as told however they continued on the 25 when i had paid it up to date I call the Telkom call centre to check and that guy told me that i must continue to pay for three months and get the data back that i paid for thereafter i can cancel it. In February 2015 i went to the store to find out if i can upgrade i was shocked to find out that my contract is only 3 months old .They cancel my hold deal which i wasn't even aware of and put it on the system as a new contract i have proof off purchase when i took the contract ,some where down the line Telkom call centre made a big mistake with my contract i have went several times to Telkom logged a complaint nothing is done about it ,its now going 5 months .All i want is to be reinstated with my old contract date cause it now time for me to upgrade i lost out as a customer i am very unhappy with Telkom mobile services .
