Bad bad service

Purchased a BOSCH tumble dryer from Tafelberg Tokai about 6 months ago and took out additional warranty. An error has now occurred and rendered the machine un-usable. Called Tafelberg a week ago to resolve as part of extended warranty. They did respond but simply passed the service call onto BOSCH. (I could have done that!) BOSCH service is hopeless ,promised to respond within 72 hours ,that period has come and gone and not a peep out of BOSCH. Tafelberg have in reality added no value at all to my purchase. So if it's after sales service you're after go some else to get your product. My pleas to them have produced no action at all.
