BAD SERVICE

Sales agent of this company sold DSTV Explora telephonically when he was explaining to me he told me that if I buy 2 I will pay R139.00 per month I had to deposit into my bank account then it will be debited on the 26 of the month. then it was installed. when the date came of payment I did the way I was instructed but into my surprised they phoned me and told me when am I going to pay my arrears then I asked them why because I'm paying every month then they said is for another explora because I took 2 then I told them that I'm not going to pay the other one because it was not explained like that to me they must organised to take it back the other one because I'm not using it . then they said they will organised to get it back then I waited for them but no one came back to me about that decision instead Air TV consultant continued to phone me asking when am I going to pay my penalties and arrears and I was telling the same thing that they must take it back the other explorer I'm not using it . then after that if I have extra funds on my bank account they debit doubled amount R139.00 they debited and they counted as if skipped other month. so they are still continuing sending me the sms that I'm on arrears instead of collecting their product that we agreed of that will be returned to them. please with this matter
