Vodacom customer care refusal to cancel my contract.

Im sick and tired of vodacom refusing to cancel my contract. Ive called them countless times. Ive sent many e-mails....I dont want your recurring R150 airtime, or your 2G data...please stop taking your customers requests forgranted. I called and explained my financial crisis and therefore was guaranteed that my contracts will be stopped. By that time I had even paid my bills in advance. I was bored when this month again I checked my balance and found airtime on my phone. Arent you tired of negative reviews? Theres always drama with Vodacom, 2016 I dealt with a ********** router contract, which took donkey years to get resolved. Vodacom, cancel my contracts, ive had enough of you. On the 1st of June I dont want your airtime or data...
