MTN AND DSV I'M DONE

So i got a notification to tell me i can upgrade on the 15th October 2020 which i did. I was told will be receiving and order number the next day but did not so i took okay during the pandemic they are short of staff. I phoned in just to find out about my upgrade it hasn't been processed. App**** for an upgrade 3 times , the 3rd time i got it right. Received the normal messages to say that your upgrade was approved . received my documents via email all to find out all my details are wrong which i gave them over the phone . Got a message to call the courier(4 November 2020) which i did to verify my details which was wrong on there system and i was told they would give me a call back still waiting on them to call. Today(10 November 202) i called the courier to ask what is the hold up and i was told no they can't help me i must call them from the phone number the contract is on to verify my details, so i told them to keep the smart device and send it back wherever it came from i don't want it anymore .. they didn't wanted to help me even MTN call centre couldn't help me either ... PS : TOOK ME 4 DAYS TO RECEIVE AN UPGRADE FROM ANOTHER NETWORK NO PROBLEM THINK I WILL STICK WITH THEM
