unable to do their jobs honestly

I have got the same problem with this bank again! last year I deposited a check and asked for special clearance they said 7 - 10 working days and it took 13 days, only when I logged a complaint with hello peter that same day the check was cleared, now its the same thing I deposited my checque on the 15th they said 3 days with special clearance and we are now on day 7, when I called they said 4 - 10 days and could not give me a reason whats the hold up, except that it needs to be cleared, the money is out of the payers account already so where is it then? its showing in my account but not available this is pathetic and I just want to close my account with them now and seek better service, please can someone make them stop the utter BS! that they feed the people that bank with them?
