Adjust your attitude towards customers

Yesterday I went to Foschini Eastrand mall to close my account the lady who was suppose to help me just started to make assumptions that the account wasn't paid up \Ma'm we can't close your account as you still have to pay the outstanding amount"I showed her proof of payment & her answer was \""you have to wait another 48 hrs then will have to come back to close the account\"" when I questioned her why I was suppose to wait 48 hrs she threw her hands & basically told me her boss advised her so then left to speak to someone"
