Poor systems n poor customer service

I had walked into mrp home @ pavilion to return 4 rod ends I am aware that I did lose the receipt as in this day and age who keeps receipts unless it comes to our mobiles so I know the procedure is to acquire a gift card to buy in future at any of the Mrp home stores I was not aware that the system or consultants where so uns****ed that them would credit my gift card n then debit the card on the same day as I was told a week later when I went to use the card at mrp on argle a after they called help desk firstly I had to wait for over an hour secondly I was embarrassed as I was told I'm using an invalid gift card I then go to the pavilion store to find out what went wrong as they advised me that the gift card will work in 24 hours as far as I know gift cards are ready to use immediately poor systems really an software upgrade is in order or proper training .I then wait 15 minutes for the consultant handling the issue to come to the front n a further 1 hour for her to get the documents to tell me that they are investigating the issue after 2weeks they investigating why they systems were down n I couldn't get my money for goods I had initially paid for on cash due to their systems n poor customer service training I am now waiting for the 3rd week for feed back n when I call in the person handing the claim is on leave how Convenient this is really the worst customer experience I had ever experienced n I've been shopping with Mrp all my life it's a home brand together with a family brand this is really dissapointing
