Pathetic service at woolworths

I have just receievd the worst service at woolworths at the Mall of africa in Midrand. Firstly, i was blantantly ignored and not greeted - and i know very that woolworths presumably prides they brand on a great customer journey. I asked the cashier Dineo to check my available credit. My card is faulty so at every other woolworths store the staff would manually punch it in. This guy refused to do that. When i mentioned other stores do it he called for the manager who also failed to acknowledge my presence and he told the cashier to try again - and no ones surprise it went through! So i told the cashier , why couldnt he just do it for the second time when i asked him to try doing it again and he said he needed the managers authorisation which i knew is a lie. And he had told me that credit availabity can not be checked by entering the number manually. I was frustrated and called him out on his lie and he raises his voice and says "its your card you must know you must replace your card if the magnetic strip breaks". So i told him he needs to learn how to speak to customers and he did not even apologise. The manager on floor had witnessed the entire heated conversation and never intervened. I have never recieved such pathetic and disgusting service at any other store before. I certainly will not be shopping at woolies in Mall of Africa AGAIN!!! we pay alot at woolies for the service and quality. Really disappointed with this store. Refresher training on the customer journey is vital!
