Whirlpool after sales service

I bought a Whirlpool washer/dryer machine at Makro Strubensvalley on 06/11/2020. I had the maintenance team at my house a week later, just to find that my brand new machines motherboard was defective.

Whirlpool 's people said they have to order the motherboard. I keep on trying to phone the maintenance department, but it goes on voice mail. I have left detailed messages and get no reaction. Couldn't they just in the first place REPLACED the machine. How long do I still have to wait. It is costing me R560.00 per week to have my washing done. This is not acceptable and I want answers please. I have no e-mail address only contact number *** Regards Linda De Ruyter (Dekker)
