Disgusted service from Pnp Store Manager

We purchased a Russell Hobbs kettle from Pick n Pay Middestad Bellville in September 2018 end November 2018 the kettle just stopped working. We were unable to take the kettle back to Pnp so today we decided to take it back but we lost the till slip. So one of the staff told us that they would be able to check on the smart shoppers card if we swiped it. So we spoke to store manager who just told me that they can't do it because it was more then a month ago. I am deeply disgusted in their behavior as I have been a loyal client of Pnp for many many years. Is this really how u treat your clients?
