Bad service from Supa quick Isando manager

Hi everyone

I had a horrible experience with the Supa quick manager, Ashleey (sp) I bought a voucher and called in, he didn't wait for me to even finish what I wanted to say and gave me an email address. Shortly thereafter I sent a friend to take in my car and redeem the voucher, He then said vouchers needed to be printed out

When I called in he shouted at me on the phone as if he was doing me a favour for balancing my cars. If I didn't have a long trip I would've canceled.

I am so disappointed .
