really bad service

I had an interesting experience now at your East Rand mall branch. i bought an iron on the 30th April, yesterday it stopped working. i took it back today to exchange it as it broke after not even 3 months. After scanning the replacement iron i was told i need to pay in R20, i refused. the store manager then came and told me the same thing, i refused again. The store manager then phoned the area manager, and after laughing about me on the phone, which i clearly heard she came and told me again that i must pay in.

Why on earth do i need to pay in for something that is faulty????

after an argument she eventually gave me a new iron but that whole experience was totally shocking.

the one good thing was the cashier Busi who was very friendly and helpful
