Absolutely pathetic contract

My term for my 2 contracts have ended 2 months ago!!!!!!! Till now I haven’t received a call with an option to cancel my contract only upgrade I had to now three times call them myself and attempt over and over to cancel the contracts, now even the third contract ended!!!! But for all 3 contracts I am still being debited the full amount for absolutely nothing!!!!this is daylight Roberry and I expect a full refund from telkom for all of these unnecessary debits and money of mine wasted!!!!
