Nonsense coverage

I am very disappointed in Telkom mobile, I bought LTE bundles and was be able to use them normally but now jiki jiki they say you have to change tariffs to continue using them. I did so but now I cannot have acess to them because where I am currently they do not have coverage and by the time I go back to Cape Town a whole 5 gigs would have expired. Their agent just told me "then you have to go to a place with coverage" like seriously why don't you fix your coverage issues instead of telling me that. I have missed zoom interviews becauee of this nonsense. Yeer maan
