Unhappy Client

The company is working in silos, departments are not in sync. You present a problem the consultant you are speaking to has no information that one sent to the same company and s/he can not log your complaint. which means every time you call you have to start from scratch getting lectures from the consultant what you are not doing correct. My case is that I have been paying by EFT I got a permission from one of the consultant, that was my mistake I have not missed a single payment but my contract has been suspended. I have sent proof of payment they do not acknowledge receiving them and the consultant you phone can not see those proof of payment because they reside in another department where s/he has no authority to pool them thru to validate your statement. Quite frustrating. I have spoken to almost six to ten consultant and each time I come to a cul-de-sac . I am baffled as to what must I do since they do not have an ombudsman.
