After Sales Experience

I have logged a service request on my microwave 40L Solo as it was not heating up anymore. - 24 June 2022 - Logged service request Ref no: 57-350255 - 29 June 2022 - Repair were completed. - 1 July 2022 Sent an email to the following as the microwave stopped heating up again. - 5 July 2022 - Repair done again. - 19 July - Microwave gradually stopped heating up again.( It couldn't heat up anything over 5 minutes and eventually stopped completely) Logged service request Ref no. 58-356452. I have not recieved feedback from the repair centre. I have called numerous times and no one can help me. This is such pathetic after sales service. I just need to know if I should cut my losses and buy another microwave as I paid for parts and callout fee as it just fell out of the 3 year warranty period.
