Worst service ever

I sent back the watch straps that I bought April that took time to be noted as received. I was told that my refund was processed on the 4th of May which I haven't received till date. I followed up and I was given POP that it was processed on the 3rd but how cause the card number I dont even recognize. I just want my money, I want nothing to do with them ever what nonsense of the service is this???
