Rma'd my 4070ti with OVERCLOCKERS and received this in return please advise

I sent an inno3d 4070ti in for rma, two days later they've sent this garbage 3050 back, saying that it's what I sent them.

They're now asking me to prove what I sent to them by asking if I took a photo of it before I sent it to them.

I have my invoice for purchasing the 4070 6 months ago from them, and the graphics cards weight is massively different, I'm getting in touch with dpd tomorrow to get the weight of my parcel I sent out.

Anyone experienced this?
