MTN DIRECT non caring and poor service

I decided to do an upgrade on one of my 3 contracts with Mtn as a gift for my daughter on her birthday. Started with the arrangements on 19 Sept 2017. I explained to Mamotso from Mtn direct that I stay in George, but the phone must be delivered to Bloemfontein were my family currently reside. Mamotso explained that I must just send a letter and a copy of my ID to my wife to receive the phone. When delivery was supposed to be done, this was a problem, so we missed the birthday gift after numerous arguments. Some time have gone by without any interaction from Mtn direct, and you struggle to get hold of Mtn via their contact center. Thus after the useless service, I told Mtn direct that the upgrade must be cancelled, as I was not going to sign and accept the phone and contract. After numerous phone calls I received a Ref nr ( ********** 34) on 20 November, and was told that I will be contacted shortly. After no communication from Mtn, I contacted them again with the given Ref nr on 30 Nov with the same comment that I will be contacted. Today is 3 December and still no phone call from Mtn. It is the second month that I have to phone Mtn to cancel the suspension as the credit limit needs to be increased to cover the upgrade costs on a phone that I have not received! I have now been a customer of Mtn for more than 20 years, and will not do any upgrades through them again.
