Suffering for someone else's error

Someone paid their subscription into my account in error, this happened in May already, you guys decided not to take your debit from me because someone had paid for me already, when that person came forward you reversed that persons error and suspended my subscription, this was not my fault, i have a debit order in place, now i have to suffer for someone elses mistake, you guys didnt even think of letting me know of the error, i had to call you guys, am still unable to watch tv even today
