Suspended account even though I am paid in advance

Please contact me asap ***. <br> <br> My account is suspended even though I have paid in advance. I have given through my debit order details yet you never try to get payment that way, I always have to try payment via an old easypay invoice yet you never send a new invoice. <br> <br> I have phoned your customer service number today already 12 times. I either get cut off or someone pretend to help me and then cut me off.<br> <br> I am suspended 12-15 times a month<br> <br> If you cannot help me can we please just cancel the whole contract. I drive alone too often to be without a reliable mobile carrier.
