A bad shopping experience at Rochester

In October 2021, I bought a set of couches from Rochester Fourways, to be delivered in a village in Ga-Mashabela Limpopo. I was charged around R900 for delivery, with the understanding that the set will be transported from the Rochester Polokwane branch to the requested delivery address in Ga-Mashabela. My order was delivered without any hiccups. On the 6th December 2022, I bought more items from Rochester, 1 3-seater couch and 2 occasional chairs. This order was also meant to be delivered to the same Ga-Mashabela address. Again, I was charged around R900 for delivery, because the items were to be delivered from the Polokwane branch. My order was meant to be delivered on Thursday 8th December 2022. But on the 9th Dec, I received a call from the sales man (Lebo) informing me that my order wasn't delivered because I was undercharged for delivery. He said according to the warehouse, I needed to pay an extra R1 500 for my order because the requested delivery address is outside of the delivery zones. I explained to him that I made a purchase the previous year with the request for the order to be delivered at the same address I requested now and I was charged the same amount he had charged for my new order. He explained that he just recently learned that the store has changed its delivery policy since my October 2021 order. Because of the steep delivery fee, I told him that I'll have to cancel my order. I went into the store on Monday 12th December 2022 for the order cancelation. Again, Lebo was the assisting. I asked if there absolutely nothing that can be done to waiver the additional cost, as I am a repeat customer. He explained that he spoke to his manager and the manager said there was nothing they can do to assist me. After capturing my refund request, I was told that I'd receive my money back by the end of December. Lebo explained that the store's policy is 5-7 working days but just to add a buffer, I should get my money around the 28th December. Today is the 23rd of Jan 2023 and I still haven't received my refund. I called Lebo last week to find out what's taking so long. He said the system the store uses to track refunds has been down since Monday (16/01/2023) and that he'll give me an update on Saturday (21/01/2023). I reminded him that I he said I'd get my refund by end of December, so the system being down for a week still doesn't explain why my refund hasn't been received yet. He emphasised that he'll give me an update on Saturday, but I haven't heard from him yet. In closing, I'm disappointed at how a big store like Rochester treats its customers. Whether you're a first time customer or a repeat customer, that doesn't make a difference to the store. I don't feel valued as a customer. I just want to get my money back so that I never have to do any business with the store again. I'd like to know how much longer I need to wait for my money because I still have to buy the furniture I had ordered from Rochester, from a different store. I'm being held ransom by the store.
