Bad service, no delivery after paying full amount

I bought a bed at dial a bed in Parklands Capetown Sandown store Monday and was told they can only deliver Thursday latest.

Later that day realized I was charged higher amount thn I was suppose to pay. Call the store next day for refund and the store Assistant who made a mistake was remorseful and what I hated is that they told their assistant to refund me out of his pocket the money. Which didn't make sense to me and the next thing I was told they had transferred my money to my flats mate account who bought a bed on account and they asked me to get a refund from her.

That also didn't make sense to me as I paid cash and they mistakenly made both transactions as one.

Cool I asked that they deliver the beds Thursday and I was told its Impossible because they are sorting the transaction issue. But asked them how is that the case as they have the money with them including delivery fee I paid.

I was referred to the manager who said it was my fault that I didn't check that I was overcharged by their store when I made a payment. AS its my responsibility to verify the amount before making a payment. Yes, I agree but how is that stopping them from delivering my bed.

The manager lady promised they will get it sorted Yersterday (Thursday and they will deliver Friday being today.

Guess what I never received any calls about the progress of the matter, I have been the one reaching out to them and now they telling me they are delivering it tomorrow surtday and when I ask for time they saying tejy can't say.

So that don't want to give me my money, my refund of which I was overcharged by and They also don't want to deliver my bed.

What do I need to do now? Is this how they treat their customers? Yersterday the excuse I got was that their warehouse closes at 5pm and their system was down hence they can't deliver.

Today called them early and at 14h00 they actually resolved the transaction issue but they telling me they will deliver tomorrow.

I have been sleeping on the floor from Monday and waking up to go to work, I have been calling them Now and again but still I'm getting excuses.

What should I for now? Sleep on the floor again w hile I paid them cash?
