Very Bad Service

I have heard the worst experience with MTN today. I bought a 30 days 20GB data, 10 day and 10 night. Usually i am able to run my business and stream with data for over two weeks. This time around the data couldn't even last 24 Hours and the customer care had the audacity to refuse to help me resolve the issue. I am so disappointed with this network provider. I was starting to enjoy their services but seems like they just the same at the others.
