Email/Refund *** -

I bought a pair of sunglasses - about a week later I was told there is no stock and the model has been discontinued - I was told they will happily refund me. Its been a month now and Ana from smartbuyglassess has been emailing (21 emails now in total including mine) me when she feels like it in the last month apologizing for delays , confirming bank details again , emailing to advise she hasn't had feedback from accounts yet... Nothing is happening.

Why don't these guys have a call center number ? This is extremely bad service. How difficult can it be to refund a client ?
