Poor Aftersales Service

Queried spare parts for my Bosch Cordless 18v Jigsaw and eventually managed to order the parts. Took 6 months just to order the parts. Parts were to come from Germany and take 2 to 3 weeks. It has not been 5 months since I ordered the parts. I have not received a call, message or email indicating the progress on the order. When I query anything, I being pushed from one person to the next. Hopeless service for such a well-recognized company.
