Very poor service

I'm not usually one to complain, but after experiencing poor service time and again from MTN Cavendish, I really think matters need to be addressed. Last month, I went into the store to take out a contract. I was told I'd need my ID, bank statement and pay slip. I got these documents and went back only to be told I needed a proof of address too. When I had all necessary forms, I began the process and was told I'd be notified when I could come back to collect the phone. I was never contacted so tried calling the store multiple times over a week (the phone was never answered) and then contacted MTN service on Facebook and Twitter. I received replies fairly quickly asking for my ID number but unfortunately wasn't contacted further. I eventually went back to the store to find out what was happening. A few weeks later I went back with a query and was helped by Saayidah - the same lady who did the paper work for my contract but never contacted me. She was rude and had a bad attitude when I asked why the extra start up fees were never mentioned to me. I spoke to the manager Iszak who responded with the same defensive tone for some time before apologising. Frustrated by unpleasant service.
