Pick n Pay Dobsonville Mall Customer Service At Its Worst!

I bought an Iron (Pineware) from Pick n Pay last year November and have taken it back early this year in March because it was not working anymore. Yesterday it stopped working again, so I returned it again today with the hope of getting a refund and if not so a replacement and I was told it will be taken in for repairs seeing that the Guarantee expiry date is next month. The customer care agent was not wearing a tag and refused to give me their name. What am I expected to use in the meantime while they repair something which is still within its guarantee period?
