FAILED CONTRACT CANCELATION

I requested to cancel 2 mtn contracts in the beginning of November so from the end of November, i do not pay. I emailed customer care and the retentions line. I asked for the process (cancellation fees etc). nobody contacted me, I emailed every day. I email again yesterday, only to get another ticket number. when people cant pay or cant afford to pay , you list them with the credit bureas!!!!!!!!!!!!!
