Business Damaging Service (Very Poor)

I have been trying to arrange 2 cash bank guarantees from late last year. To date none of them has been done despite the fact that the funds are in possession of FNB. firstly I was made to complete wrong forms (twice) and objected when on the 3rd instance it was clear that the other form was also not right. next came a series of amendments that I needed to make to a covering letter (despite the fact that FNB already had all the information). this also not taking into accounts my pleas that the matter is extremely urgent. each time I phone Keegan he does not pick up my phone or get back to me after leaving a message. The problem is that one of the guarantees is for property transfer as I am a conveyancer in this matter. The client has been waiting ever since and because of these unwarranted delays that are also very embarrassing for me to explain to client, i am unlikely to get any further work from this client again. As this is a new firm that I have just set-up, a service like this will make me loose the few client I have and if it goes down, I may not be able to recover again.
