Mr Shopper

I have been a Mr Shopper buyer since lockdown Service has been on time, but has now dropped below acceptable. I purchased wireless headphones which indicated they could be used on a TV. You received the item but only opened the package after one month. Then I found out it didn't work on TV. I am aware of the return policy, but I thought an explanation of the reason for the delay could affect the return in my favor. However, it was rejected on November 25th. I sent emails and called the only number available. The mystery consultants have misled me by saying they can't or can't solve the problem. I am still waiting for them to come and collect the headphones and send my refund. It goes without saying that something in the Good Customer Service system has changed in Mr Shopper
