Ridiculous customer service!

I’ve purchased 3 items on the MRP app for the first time. Using the SID instant payment method I was redirected to my banking app to authorize the payment. When payment was authorized the money was deducted out of my banking account. I checked the app to get my order number and proceed the process, it stated “invalid address”. Mind you the money was already taken out of my account. With that whole experience I have contacted numerous people of Mr Price. I spoke to Yvonne, Zintle as well as Thembelihle but to no help, they apparently can’t see such a transaction. I have sent my bank statements to them as proof that I paid for these items! Their services are pathetic! I am so upset.
