I have a valid plan of 200GB, I wanted to try a new tariff of 2TB or it works in a family subscription, after that I returned my tariff plan back to 200GB but the money was immediately written off $ 9.99. can i stay on the old rate and get $ 9.99 back
If you made the change before your payment method was charged, then you wouldn't be charged extra.
great, but why did the money go to my account?
