Bad service

On 2019/05/10 I upgrade two of my contracts with MTN after 3 days I had to phone them to get the 20 gig anytime free data loaded. It was only done 2 days later in my one contract. After checking the other number i also found that the 20 gig and 14 gig entertainment pass was not loaded on the contract. Since then i have been phoning and getting told it will be loaded within 48 hours. But it is now more than 3 weeks and still nothing. I have been with MTN for more than 20 years but this is a new low for them.
