Horrible experience at Mr Price

Yesterday my family and I decided to go to The Mall of Africa to do a bit of shopping. We decided to go into Mr Price; biggest mistake we ever did! We spent over an hour at Mr Price trying to make our purchase. The staff were not helpful as after making a transaction, I was told that there they could not read the transaction due to network issues and suggested I repay the amount again. Keep in mind that I had already received a notification from my bank that a purchase was made from my account to this store and was approved. I showed the sales clerk this notification and I was horrified to hear the response from the sales clerk. I was then told to leave the store without my goods and come back as soon as I was done going to another store. I decided not to go because the store was closed therefore I didn't want to take any chances that they would or wouldn't open the door for me. At that time, the manager was not around but promised they would call him to sort this mess out. To my utter dismay, after waiting for him to arrive; after waiting for his staff and him to talk it out and try find a solution; after waiting for him to actually come communicate with me as the manager, he decided to stand far away from the scene and let his staff deal with me. After complaining to his staff about lack of customer service from the store and the manager and threatening to have him and the store reported, did he actually step forward to offer some form of communique. He told me that it's not the first time this happens to a customer and had already spoke to the head office about the terrible network they were using yet the head office has been ignoring their pleas. As a customer I feel I'm the one at a loss as I traveled 47Km from Meadowlands to Mall of Africa and another 47Km to go back home using my own fuel only to be dissatisfied with the service from Mr Price. I am really disappointed in Mr Price from Mall of Africa.
