Mr price rosebank

I bought an iron on account some time back. Not six month. Lost the receipt. Aske the shop attendees a lady to assist. To check my account as to when the iron was bought. They refused saying processing the iron is bringing Corona virus to the shop. The iron is still in the box but just went cold. Account is up to date, and they also said they can't check their system as it does not have account purchase history. The iron has two year warranty and as an account holder I thought I will be protected. The experience was bad and really bad
