I currently have Internet 750 service and am considering moving to the Premium Internet service.
However, since last week, I reported a problem with the 750 speed as it is below the service threshold.
I reported it to T-Mobile and they tell it will take more than ten working days to receive an answer.
I don’t find anywhere to enquire if I upgrade to the Premium service and I am still below the threashold of fault, can I downgrade again without penality until the problem is resolved?
