Disgusting customer service

I’m appalled by the service I received from house and home Gateway. I layebyed sofas in April and from my knowledge of someone lay yes an item it’s to be set aside for that customer. On 06/8 I paid the last outstanding amount and was told I would get my sofas by Thursday on 8/08. On that same Thursday I went to the store to pay for delivery and then all of a sudden there was no stock and I was told I would get my product the following week and the end of the week. I went to the store on Tuesday the following to confirm ETA And the manager confirmed stock will be coming from Newcastle and should be delivered by the weekend of that week. Saturday morning I received a call from the sales rep telling me I need to come to the store and choose another design as there have been delays mind you I’m using my own money to travel to the mall, money I had not budgets for as I had already paid R350 for delivery too. I told the sales rep that I will be leaving and should contact them regarding a refund but he did not bother to tell me that I need to sign for refund and also provide proof of purchase so I had to now again Uber from the CBD to Umhlanga using my money again. I need my refund to be done asap as I’ve been inconvenienced as I’ve had to make another purchase cash for the same amount at another store and they still have the audacity to tell me that they will refund me when they have cash meanwhile I’ve never paid cash but used my credit card. The staff is *********** and the manager does not want to take accountability as when I asked to speak to him he was nowhere to be seen. I’m very disappointed in the service from that store and would like for whoever is in a higher position in management to sort this out promptly before I escalate the matter to higher authorities.
