Unresolved data allocation issue

On the 12 of each month, MTN allocate data to my home router. This they didn't not allocate as always. On the 13 sept I phoned their call center to report that there is no data allocation for the month of September. They kept on resolving the ticket. When I call again asking them why the ticket is resolved while issue is not resolved on my side, I was told they will reopen the ticket as the previous one was assigned to the wrong department.

Same story happened the ticket was resolved and when I call, they said the data was allocated, on their very own app it shows no data is allocated. Month they will be debuting my account for something I didn't even receive. This is worst service ever and it's affecting my work and I have to spend to make means to work. I need an explanation and the issue
