REFUND HORROR

I am very upset with the service at Pep in kenilworth. I bought a cable and i didnt check the description it was wrong. I then wanted to return the item and they told me they dont have money to give me. I went back the next morning wanting to return the item they still had no money to do a refund. So i asked them if i could leave the item there so long cause i work in the mall i would return when they had money and everytime i walk pass there is a long queue and im at work i dont have a lot of time and their service is terrible and and they take very long at the till points so today when i returned the item was gone and i think they took the item for themselves because now no one knows where the item is and even the manager said its my problem. Im very upset its ongoing terrible service now they are being ****** also cause they remember me but they pretending as though i came to do the refund already
