Bad service

I am astonished at the bad service I received when buying a product and wanting to return it. I bought a MyGica TV box and logged the return as a faulty item by mistake. I was then advised by an agent to log a new return as "I changed my mind" as soon as I had the product back, which I did. At first my return was declined and when they finally collected the item after around 4 failed attempts I received an email saying my return was declined and the item is retured to me once again?!?! This after I did exactly as their agent advised me. Now, after all these issues the item I actually want is out of stock.
