Do not use MT N

Consultants from MTN contacted me regarding the upgrade of my contract - explained that I am paying for the contract but the contract is in someone else's name. Every time they tell me that they must talk to the account holder and every time the do not contact the the person. Daniel (if it is his real name...) contacted me and I explained the whole situation to him and how all consultants do not call the account holder. Daniel then explained and listened to what I what on the new contract - he offered me 3.5 GB of any day data and 1.5 GB night time data. He contacted the account holder and delivery for the new phone was arranged. On 16 Nov 2019 received my new data... ONLY received 1.5 GB of data. What is use of upgrading?????
