Whatever happened to customer service???

For Christmas my daughter gave my partner & I each a R200 gift card. I also have R50 on an old card as well. On the 30th we went to Edgars in Festival Mall & knew exactly what we wanted. We arrived just after the store opened & went and got what we wanted & went to the cashier to pay. WOW!! She used the one card & couldnt use the 2nd card for some reason, so the transaction was cancelled, she tried again with the other card, same thing happened. By now, Prince the mgr had been called only to find out that they were off line ONLY for the gift cards! He said he would reload the money back onto the cards in about 10 mins. An hour later I was still standing. I have a major back problem & by that time I was in agony.... NO appology NOTHING!! I lost my temper & threw the cards at the cashier & stormed out. Once home I phoned Prince & he said he would ensure the money gets loaded & call me back! Never did.... On the 5th or 6th I was back at the store.. Prince gives me a card with R400 on it... NOT my original cards & not the R450 I had! His excuse, they couldn't find the cards! Edgars is *****ing from the public and dont care! WILL NEVER SHOP FROM EDGARS AGAIN!! I am disgusted!
