Horrible after sales/return process

Bought an item from them in December, called to log a return was told it’s third party and they will contact me for a return. 11 January no call and I sent an email. Promised to call me back to resolve, till today no one has called me, I still have the item and no return logged, this is a month later!!!!!! I’m over this horrible customer service. NEVER ordering here again, I’ll stick to Makro because previously I had to return Heater to a store 4 times and it’s still faulty. I’m over this store
