Shocking after sales service from Bosch

Shocking after sales service from Bosch. Our dishwasher is still under warrantee and after almost a month of attempting to get it repaired or replaced Bosch still has not come back with a solution. After getting in touch with the Bosch call centre they did not as much as have updates on their system regarding the process thus far. A technician was sent out to check the dishwasher faults, only to tell me almost 2 weeks later the service manager wants to get a second opinion on the repairs for the dishwasher but Bosch have no history of this linked to the reference number when I phoned the call centre. Bosch is meant to be a premium choice as far as appliances are concerned but the after service is terrible. A call or follow up goes a long way when it comes to matters like this, to this day I am struggling to get adequate feedback regarding why the repair was not done after a technician was sent her, and I still don't know when the second technician will be on site. The feedback is that they need to find a technician for my area. It is going on 3 weeks without a dishwasher now.
