I opened my new account and the payment less than I paid.
How do I solve this before the next due date?
Which means my billing history is incorrect from the start?
Do I go back to the service centre where I got the plan?
What do I have to have to proof I paid a larger amount with debit?
Thanks for the clarification. At this point, I'll believe we'll need to take a look at your account to figure out what's going on with your account.
I'd suggest you contact us using any of the ways you'll find here. Alternatively, we can send you a PM.
Let me know what you'd like to do!
