Tesco was the main store for evri drop off. Why all of those matter my question was just how should i contact them because Amazon is asking me for a proof or my return.

Amazon was the one who give me the choice to return it, and the single one was evri. And i do not have that label from Tesco, i thought they will send an email recipe or something...

I end up with a vacuum cleaner from Amazon, it was broken when I open it up. After 3 weeks i have no response from Amazon about my money back or a new product. I lost my tracking number from evri (i had just a recipe from the lady from that Tesco express) My question is, how do i contact evri about this or what should i do... That vacuum wasn't much but those were my money and I want the item back or the money..
