Hirsch Appliance Services - Hillcrest ...very poor service

My eyelevel Whirlpool oven required parts replaced so Hirsch Services - Hillcrest came to assess the problem on 17 January 2019. The estimated cost of R 2 423 was paid upfront on 04.02.19 so that the order could be placed and I was then told that since the whirlpool parts are not available in SA they would have to be ordered from Europe at a delay of 6 - 8 weeks. I don't recall the exact date the service man came back to the house to install the part that had now arrived from Europe, but it was at least 6 - 8 weeks after payment. He wasn't there 5 minutes before looking at the part and then said there was a problem, didn't even have to open the oven door! He made a very hasty retreat and mumbled that a part hadn't been ordered and when I asked how long this would be, he said 2 - 3 weeks....what a joke, if the other part took 8 weeks, why would this be quicker...needless to say, I was extremely annoyed. Someone messed up the order, no apology, no follow up. Today it is exactly 14 weeks since I made the initial payment and I have still not heard from Hirsch Service Dept ... the service in this particular case has been extremely poor. I also don't understand why, when we can order things online and courier almost anything to our doorsteps in a matter of days, that we have to wait so long for a small part to come from Europe. I would rather pay the extra cost than go without an oven for 4 months. Needless to say, I will never buy Whirlpool appliances (mine came with the house) and I will have second thoughts on using Hirsch's appliance services again.
