Edgars Heidelberg mall stuffs up yet again.

I Went to the Heidelberg mall store to make a payment on my account. Firstly the female cashier was quite rude. Secondly, there seemed to be a problem with their system as it kept refusing my payment. Why would edgars management upgrade to a non-functional system? If their system doesn't allow for one to make simple payments on their accounts, then why is the store open? Perhaps this complain would reach a higher level of management that could assist. My payments declined twice at edgars, I thereafter made numerous purchases at other stores at the mall so it definitely was NOT my bank. Before getting your credit department to call me regarding payment, fix your issues. I don't have the time to keep running to edgars due to their inefficiency.
