Poor service

I wish I read all the reviews before going them. They will call and call you before all the process. When you want them, you will never get hold of them. You will send and resend emails and they will come back to you at a very later stage. They made empty promises, I was assured that no creditors will debit my Acc and yet I am sitting in a minus and they debited their monet from my Acc. Now they telling me, I must wait for 15 working days for the money to be reversed, and yet I communicated with them 1st day after my pay. What must I do as I am even more broke, that I am also reconsidering terminating my contract with them and try else where with a company more proactive and reliable.
