Unsatisfied customer and unfairly treated

We opened an account at House and Home Potchefstroom branch...we were assisted nicely the account was approved. On approval a deposit was requested...we paid the amount. We told at the store that the first debit, should be paid in store and the second one will automatically go off. We went to th2 store to sign a contract and to pay the debit, to our suprise the account was canceled days after the deposit was paid. To our suprise no communicae was done nothing, we left the store so disappointed.

The lady from the shop tried to call and give us answers. Can you believe at grating department they dropped the call and say the client is over committed.

OK...it's fine if we are over committed but why was the account initially approved? Why did they accept our deposit to Later cancel with notice? We are so dissatisfied and unhappy.
