Worst after sales service

I bought a Whirlpool washing/dryer combo from Makro in December 2019, cost me over R7500.00 as I took an extended warranty as well. In Jan 2020 the machine broke , giving me a fault code F05 and I logged a call for it to be repaired. The technician came out and said he can't find anything wrong. In December 2020 the machine starting giving me hassles again, this time it gives me a F13, so I logged another repair call. So on the 7th January 2021 the technician came out but did not do the repair as he was waiting for a part. On the 11th the technician came out in the morning and did the repair. On the 11th when I got home the machine was still giving a F13 error code. I contacted the technician on whatsapp, said he will come around and have a look. By the 19th of January 2021, after numerous messages, there still was no one there. I ended up Calling Makro, speaking to Jonathan, he said he will sort it out. The technician came out a day or two later. On 1 February 2021 the machine once again gave me a F13 error code. I send the technician a message again with no response.

Today 05 February 2021 I phoned Makro to resolve the issue, and I get told that there is only one call logged and that the original called was a waste of the Whirlpool technicians time cause there was nothing wrong with the machine.

Now I am sitting with a machine that means nothing to me and I have to put up a fight to have it replaced.
