Hirsch's waranty

I bought a Phillips coffee machine at Hirsch's a year ago, two months ago the light come on to say the water filter must be replaced We shopped around and even contacted Phillips by email and phone to enquire where we can get filter, no filters available for three months to a year was the response The machine stop working and we returned it to Hirsch's Centurion where we were told we're dishonest by using the machine for a year and now return it for a refund The sales person said they will send it in for an assessment, I was informed a part is broken and they will replace it, then another call and now there is second part broken but the machine will be back on the 14th April 2022, went there this morning, no machine? How can they Hirsch's sell machines knowing full well no filters is available, they co incidentally received a couple of water filters but was told to buy one because they are fast movers, I can't make coffee with a water filter I offered to buy another brand if the give me a good discount and was offered R1500 off a machine costing R14499!!!! I will not shop at Hirsch's again as they don't exchange faulty equipment and level of professionalism
