Lack of service after payment was made almost two months ago.

I cannot believe that I have had to pay for a repair that is not done even though payment was made 28 March. My Service Record number is #380,646. I emailed this business twice in two days on the 18th & 17th with no acknowledgement of receipt of my mail nor any responses. This is a total *******. I want my money back or my sunglasses repaired immediately.
