Bad Service by Accounts Department.

Terrible service by the accounts Department. Quick too answer when i sign up, but never return their calls when i have an acount query. They canclled my account after i explained to them that i get paid o n the 7th of every month and that their payment would be late by a few days every month, they said it will be fine. Now they cancell my account even though i have paid every month. Over and above this, i get promised by numerous managers from diffrent departments that i will get a call back...but no ones seems to care!!!!
