Incorrect parts, no refund without invoice

Good day

I purchased a set of rear drums for my Citi Golf between Jan-March last year at your centurion branch. I did not have time to install them due to lockdown and moving house etc. Yesterday I finally got the time to install them and when I opened the box, it was drums with 5 hole (it was for a polo).

I went through to your Randpark Ridge branch as thats where I stay to see whether I could be helped in anyway. They said I need to go to Centurion, I called Centurion branch to explain the situation and they said they can't help me if I don't have the invoice or the date that I purchased it. I threw all those slips away as I moved house and took it for granted that the sale persons at your branches know what they doing.

So because the car was stripped I had no choice but to buy the correct drums at the Randpark Ridge branch yesterday.

Now I'm stuck with Polo drums that I can't do anything with? So disappointing for a big company like this that I've been supporting since 2006, it really leaves a sour taste in my mouth.
