Loop'd Ear Buds

Bought Ear Buds in December last year of which one of them didn't work. I then contacted them on the 3rd of March this year telling them about it. They then advised me to log a return on their app, which I did. Until now they have been promising me about getting back to me regarding my order to be collected and exchanged maybe but they've been giving me the run-around. I don't even know if my return was approved to be granted for collection in the 1st place. I bought these Buds with alot of money but they can't even help me. Such appalling services
