Glass replacement for gas hob-Bosch Siemens customer care

I have been waiting for Bosch to arrange a service provider since the beginning of February 2022. I have spoke to many consultants regarding this and they all promise the same thing but have never kept their promise. I know a lot of people around my area who would be able to do the same job but Bosch insists on using a a service provider that is based is Durban which is about 600 km away. Bosch customer care is useless. I’m not sure why they are still open because they don’t help at all. Im so dusgusted by this, it was my first time buying their products but I will never but anything from them again and I’ll discourage everyone I know not to do it either.
