HORRIBLE ONLINE AND STORE SERVICE

Hi there. I received the most ********** customer service from not just the online, but also from the actual stores. So I normally shop online using the Mrp app for clothing I need, because sometimes the stores in my area don't have the stock that online has. So I paced an order for a Knit pul***** on Tuesday 09/08/2022. Everything went smoothly, order was confirmed and everything, got the email stating that. So to my surprise this morning, I I received a email stating that my order was canceled due to there not being stock of the pul*****. I then phoned the cuatomer care to Enquire about this cancelation. I asked them is there no way for them to source the product for me from another store, as one of my previous orders items were sourced to complete the online order, only for them to tell me that they don't know and that I must ask a store to assist me. I then ask this agent is the customers needs to be met and isn't customer satisfaction what all retail stores are striving for, and she told me she doesn't know what to answer me. I was then put through to a store, the Mrp branch in Walmer Park, and ask the sales assistant if it's possible to do inter branch transfers between stores. I told her I did the online order, but it was canceled and that they didn't have the stock. She told me she will ask her manager. Couple minutes later she tells me that her manager told her to tell me that if I want the item, I have to phone the store Myself and arrange for them to transfer it to them. What the actual hell?? Since when do customers have to make arrangements themselves? I really am extremely unhappy and upset about this whole ordeal. I have been a Mrp customer for several years and have always supported you. They are quick to phone people for accounts that's due for payments, but can't even assist with this? I will be paying my account in full and be closing it. Clearly based on the service received, they don't need my money. Thank You
