False data from MTN -UNcapped is not really unCapped .

I took a router with MTN in 2022 - since them i have used it uncapped / unlimited . Since last night my network has been bad then i decided to call this morning to ask why . I was told that i have ran out of data . I did not understand why and how as i am on uncapped data. The 400G that im told i am given is news to me . Why does MTN sale on false terms n conditions . I was forced to buy data today so that i am able to work because i dont have wifi. That means no TV for me because i dont have data . MTN please sell products with honest packages.
