Deplorable Service from Whirlpool South Africa

I lodged a repair for my oven with Whirlpool South Africa on 16 April 2016. All of my details were taken down and within a week the contracted technician Monty came and uplifted the appliance from my home. After numerous phone calls to the technician, whirlpools customer service agents and managers to this day 12 August 2016 I still do not have my oven repaired. There are endless excuses by the customer service centre that they will investigate and revert to me and by the technician that he is awaiting the parts. Whirlpool South Africa has never once in all this time ever contacted me to provide me with an update or an apology. It is sad to receive such service when every major appliance in my kitchen is a Whirlpool product.
