The T-Mobile Website Gets Stuck When I Try to Pay My Bill

I just went through this with a new prepaid account. I was unable to complete the process when attempting to pay my bill, and got an error notification on the last page. Be careful, people, because I made several attempts, and despite the fact I was getting a server error on my end, the process was completing on their end, and my account got hit five times for my billing amount. It's been a week and I am still waiting for my account to be credited, which is a hardship as I'm on a limited income right now, like many out there. Whatever you do, if it doesn't go through the first time and you get an error message, don't keep repeating the process or you may end up with hundreds being taken out of your account.
