geez a call centre agent so rude

I have a problem with your agents,actually from the sales person . who decided to offer me a contract.now my sim card is suspended. I called on Monday spoke to Lee who said they have listened to the recording and these r the pointers they got From that call, the sales person was in a rush, the customer wasn't concentrating ,the client wasnt advised of VAS still I was offered a contract. Never ever have i received that airtime but my money was being debited, i stopped it and reversed. Now i asked to speak to a manager i was put thru to Darryl who said he was a manager, unfortunately he **** too. Promised to call me before close of business on tuesday, to this day,he hasnt called. I called today spoke to these 3 ppl, Laura, Tumi, Shevone. Who refused for me to speak to a manager. They decided to release my call. LAURA is even worse , decides that she will speak anyhow with me even when im speaking she interrupts. Even went to an extenr of telling me that all managers r busy and she wont give me her surname. I dont understand how Mtn could even give u a contract to do their sales.u r pathetic and lack customer service.u weren't trained properly ,I guess that's how u conclude shody dea
