VERY UNHAPPY CUSTOMER!!!

I am appalled by the customer service I recently received from Midas at Sky City from Refilwe!! I bought a car battery (Sabat) on the 20th of May 2021 for a BMW, and it started giving me issues just after 2 weeks. I then discovered they sold me an incorrect battery now they expect me to pay more for the mistake they made after I had specifically stated the make of my car. Furthermore when I opt for a refund an my old battery back, I am told that it is not possible after the emotional distress they put me through with the battery that left me stranded in the middle of nowhere!!! I VERY DISAPPOINTED WITH THE CUSTOMER SERVICE I RECEIVED!!!!
