Terrible, poor, horrible, awful service

A payment allocation that has been hanging for more then a month already but they keeps on calling for the outstanding payment. When I call them to help with the allocation, non of them can actually do something. Done doing business with them. As soon as this is settled, which can be years from now, I will simply close the account and oh boy, they will never see me again. Hopefully when this account has been handed over, they will probably allocate the payment but my business goes elsewhere. They don't even deserve the 1 star rate
