MONDO AND MTN ARE **********!!!

A few months ago I got a call from mondo they offered me a Mtn contract for 199 a month. Numerous times during the recorded conversation I asked the guy how much the Monthly installment would be he assured me it was 199 per month I asked about extra costs he said bcz it was mid-month when I receive the contract only R69 would be taken for that month and then R199 every month after that. I reminded him that he said the phone call was recorded like he reminded me when I answered the call that it was recorded. But he assured me ONLY R69 FIRST MONTH THEN R199 EVERY MONTH AFTER THAT. Month end came and my bill was R325. I didn't pay... I tried to get hold of Mtn on thr land line I send numerous emails and all they could say was that it's pro rata charges which i was never told about even after asking to make sure. I was not willing to pay bcz like Uve read I asked to make sure. I've been getting final notices for the amount of R1295 for the past 3 months considering that I only used the contract for the less then half of September month then it was switched off. According to my calculations 199 x 3 months should be 600 according to our agreement. This is ****************.
