begging to pay an account

Our story goes as follows , my Wife was told that she has an outstanding amount with American Swiss by our bond originator ,as we are applying for a house bond .We have been trying to find out where we need to pay the outstanding amount too .After 2 weeks of numerous phone calls to American Swiss customer care and Accounts department. we still don't have an answer , we keep getting told that the account was handed over to MBD, and we need to contact them .Every time we phone the number given to us ,we get the same answer ,"sorry maam your account is not with us"we ask everytime are you sure !!! and the answer yes maam !!we then call american swiss back and the y still dont help !! all i need is the paid up letter so that i can get this bond approved as it really is going to be the reason we loose the house !

Pathetic service really , and to top it all off , your staff are rude !
