Horrible service

I bought a dress from spree because i was not fami**** with their sizes the dress was small. I requested to drop the dress at the salon that is close to my office so that i would be refunded. Firstly when i dropped the dress it wasn't scanned the gentleman who assisted me told me that everything is done through sms so they will send me an sms of which they never did. A week after i went back to the salon the dress was still seating there and the same gentlemen told me that he wasn't also sure when it was going to be collected. I phoned the customer service and i spoke to a consultant who send an email to the courier company requesting them to collect the dress so that i can be refunded. It was already 2weeks and i phoned the customer care wanting to know what was happening with the dress then i spoke to another consultant who told me that they haven't received the dress but she's going to send a request to the account so that they will credit me which will take probably 2days . Its been almost 3weeks already i haven't been refunded i have phoned 4times already of which everytime im told someone will contact me . Im really loosing my patience
