no delivery

I did an upgrade with MTN 2 weeks back, all was approved but no phone has been delivered yet. Instead my aim card was suspended because of a fee I was supposed to pay yet no one told me about, the sim was sorted but no delivery yet. A lady phoned me on Monday telling me the work address was said to be incorrect,yet they have delivered b4 to that same address. I phoned MTN 808, spoke to William who very nice but phone got cut off on transferring, phoned back and spoke 2 given who spoke well also and transferred me, spoke to Nhlanhla who spoke like some1 was forcing and said she was transferring me to deliveries when I was finally transferred the guy said they don't do deliveries bla bla and gave me a number 2call. MTN has been sending me 4rm pillar 2post, the number I got gives same options as 808 can't I just get my phone delivered coz service wise MTN has failed 1/10 poorest service ever.
