Very disappointed with the Pro Shop online service

I have really been struggling with the Pro Shop Online the last few months. I have been ordering from their Online sight for years and I always received good service with quick delivery and good communication. Now for the last few months the delivery takes between one to three and a half weeks where it always took a day or two. I know they state that delivery time is between 5 - 7 days, but three and a half weeks is insane. A couple of months ago I ordered a couple of shirts and after a week or two my order arrived. One of the shirts was not the shirt I ordered. I called the Pro Shop and the lady said they will send the correct shirt. After the third time of sending the incorrect shirt the lady informed me that they do not have stock of the shirt I ordered and that they will refund me with a gift card. I paid R250 for the shirt and only received a gift card for R240-60. I know it is only a R9 difference but it is more about the principle. I expect to get a gift card for the same amount that I paid. Now the last time I ordered online someone from the Pro Shop called me after 3 weeks and informed me they did not have the driver I ordered in stock and are waiting for the stock to arrive. I informed them that I already bought another driver, because it took so long and that they could refund me the money. They said they would do so and the money would reflect in my account within five days. After the call I realized that nobody took my bank account details and thus no payment could be made. I called them back to follow up and every time the lady told me she would come back to me with a response within 5 minutes. This also never happened. A week after the person called me regarding the driver that was out of stock I finally received an e-mail asking for my banking details. I sent my details through and it has been three days (9 days after I was promised I would receive my refund) now again and still no refund. Then two days ago the shirts finally arrived that I ordered three and a half weeks ago and again it was not the same shirts as on the photo on their website. I was told that it is the same shirt and that it only looks different, because of the way the photo was taken. This is also a lie as you could clearly see the shirts advertised on the photo had stripes and was a silky material where the shirts I received were plain and was more of a cotton material. They then informed me that they don't have the types of shirts that I am looking for in stock and would refund me. I sent them an e-mail again today and asked when I could expect my refund. I received a read receipt, but never a reply. In this year alone I bought over R53 000 worth of equipment (Epic Sub Zero Driver, Grips, Gift Vouchers, Evnroll Putter, Ping I200 irons, Cobra F7 fairway wood, Callaway XR fairway wood, Ping G hybrid, Ping Glide wedge, Titleist SM6 wedge and a lot of clothes, ***** and shoes) from the Pro Shop and Pro Shop online and this is the service I get for the last couple of months. I am not satisfied at all. You have lost a loyal customer.
