Poor feedback

I have been sending a number of mails to Anthony, he is the Manager.

I settled my account more that a week ago, and I was promised as soon as I have made payment I should send the proof to Anthony in order for me to get my settlement letter, to date I have note received it, i have sent Anthony numerous mails and tried calling no reply.

I cant believe you treat your customers in this way. Why is this such a damn mission to get a settlement letter?????
