Adidas — Refund was not sent after pick up

I online shop 2 items from Adidas, one of them was not to my expectation, so I requested a refund.
Pick up was made and later confirmed by them on January 27th.
On February 10th I was told the refund was sent and should be on my account within 14 days.
March 27th I told them I have not received it.
Then again they gave me a 14 days notice which again I did not receive and complain about on April 11th.

This is just the worst shopping experience I have ever had.
those people are big cheaters !
