I got a refund from My Cozy Life Store, and It was very fast because I opted for cancelling the dispute as asked by the seller.
I decided to leave non feedback, nor negative nor positive, just NO, because this story has exausted all my patience.
I ordered the meter just because I was curious, but this adventure took too much of my time.
I've found other sellers on AliExpress who have shown respect for me as a customer and have done their best to solve problems, so it's not AliExpress' fault, and I will buy there if needed.
Best regards
