Disgusting service and making empty promises sis

So I opened an account last year with best electric.. I bought a 58 inch tv, machine and coaches and all those goods totaled to R2000 and something every month.. First installment was effective from November of which that was done and ever since my payments have been successful to my surprise I got a call from the furniture shop in Daveyton Mall where I was advised I need to come so that they can re open my account as one of the agents didn't punch in my salary correctly therefore we starting afresh the entire process and the goods must be collected.. Was frustrated and so annoyed as to why is it my fault.. Well all happened went to the store and started everything afresh and I was advise the past 2 installments I paid will be refunded to me by Saturday the 16th..ive been waiting for my refund.. When I call the store am being told there's no money yet as there's no payments made basically the shop is not making where as I was promised ill get my refund on the 16th.. I am such a disgusted customer as we speak infact wish they could come collect thier goods and we cancel this entire deal
