**** and horrible service

I recently had a horrible experience at your shop. I was assisted by two ladies when I was looking to buy a recorder with my revolving credit. On the 9th of August I made a purchase, they let me make payment knowing they don't have the decoder at hand. After making me pay they made an excuse about the manager leaving with the key of the cabinet were they keep the decoders. I was told they will call me the same day when the manager comes back to the shop. I waited a week and a day for their call and it never came, on the 18th of August I went back and when they saw me they pretended to look for the so called key, they made up solutions about sourcing the decoder from other shops but I would have to come back for it. That when I decided to cancel the sale , and have the money returned to my revolving account. Since it was a Sunday they said they will do the call for refund on Monday, I left the receipt at the shop and was not even given a reference for refund, I called connect finance to track my account and found that 5 days later there isn't a request for refund that was made to them. Are they trying to **** me? There is no way I am dealing with them again. If I don't get help here I will have to take this further. The service made me sick and angry at the mistreatment I had to endure.
