PATHETIC & VERY POOR SERVICE

I received an sms a on the 7th March 07:03am that DSV has my MTN order and will contact me soon to make a delivery appointment (these phones were ordered already on the 1st of March). I then got a call from ********** 400 at 12:01pm but I missed the call, I then called back just as I missed the call but could not get through after several attempts and eventually on my 5th attempt I spoke to someone and that person asked for my ID number and will get the person to call me back. 08 March no call back, then I called at 10:12am to again be asked for my ID number and they will get the person to call me back. Eventually I get a call at 04:05pm to confirm my delivery which I was told someone would be in my area Airport industria on Monday to deliver my phones.....Guess what its Wednesday 13th March 1:00pm and nothing yet!!!!! I've been with MTN for 8years and always upgraded my phone with excellent service delivery from RTT no more than 3 days.
