Worst service I've ever received

My experience started more or less a month ago when I tried to order a desk and chairs, but the app kept throwing me out. I then went to the store for help. The employees didn't know how to fix the problem either and didn't offer much assistance. I asked them if they can at least call for help. They returned saying the app is offline. Nothing they can do about it. The right items were unfortunately not in store either. Someone went to check and never came back to say that. My sister had to go find out. I went home, tried by myself on the app for several days, but the problem persisted. Then I called the toll free number and was told someone from the technical team will call me back, but it didn't happen either. Eventually on the 1st of March I figured out the problem myself. It was that my old MRP card number was still on the app. No one said that can be a possible reason. I updated it and got my order confirmation. The email said it will be delivered by the 10th of March. I tracked it several times and up until two days ago it just said submitted. Yesterday it was gone. I called client services that said there was a technical glitch and someone will answer in 48hours, then it will be resubmitted and take another 10 days. I explained how unhappy I was and he has been the only person that really did something to help or so I thought. His name is Siphamandla. He said he'll send a confirmation email with the detail by COB yesterday. Nothing happened. I've also tried Whatsapp, but it didn't help. I really think you should look at the assistance your staff in general is giving. I know MRP is very big and doesn't need my business (I've been a loyal customer for years), but it is a bad place to be when your staff doesn't care whether you make a sale or lose a customer.
