Online return nightmare

I bought a mixer ...online from the pay just now app. When the mixer arrived it did not want to switch on. Packed it back and then put that huge box in my boot to return to a store. When I got there, I was told they cannot help me and the item must be returned online. I called Edgars who confirmed this. Sent them the pictures they asked on 5May. Item collected. On 9 May I received confirmation that Item received and should be booked in within 72h. No comms from Edgars. I have to send follow up mails all the time Was told that the item is referred back to supplier and I must wait on the supplier test to be finalised before I can get my money back!

I have a Huge Problem with that!

I did not buy this item from the supplier but at Edgars online.

When I plugged in the device there was no power.

Edgars should have tested it when received and refunded my money then take the matter up with their supplier. NOT INCONVENIENCE THEIR CUSTOMER AND KEEP ME WAITING FOR A REFUND PENDING SUPPLIER FINDINGS!!! This is total and utter bull****. It's been more than a month since I purchased this item and weeks that I have been waiting on a resolve.
