Poor service from Lewis stores

My mother is a customer at Lewis who bought a washing machine from Lewis branch and the machine is still under Warranty. On the 24th of January we called the Bloemhof branch to log a call for the faulty machine, we were promised that the Manager will call us back but that never happened. After attempting to get hold of the Manager a couple of times, I finally got of another Manager by the name of Irene who was very rude and treated me like I was begging for service instead of treating me like a customer. I told her that I will call Lewis Head Office and she told me to go right ahead.

I called the Customer line and spoke to a lady named Delsia. She told me that the Technician will come through the following week, meaning the week of the 6th of February, but no one came.

My mother spoke to Delsia again on Monday asking why the Technician has not come through yet, she said she will follow up and let her know but still she never came back to my Mother. I called her again on Wednesday, the 15th and she had a gentleman from the Orkney Lewis branch on the line and they both promised that the machine would be picked up later that day, but still no one came through, no one has even called. We have been waiting for the Technician to come through for almost a month.
