I bought a #bosch automatic mower with an offer of installation. Operator very unpleasant offers on the phone! After validating my offer and following the procedure, a month later I still have not been contacted by the installer when the deadline was 15 days. The operators tell me that it is the customer to relieve the problem! and call their marketing company who set up the offer !!! Serious ???? !!! And in addition their company Districom Sales and Marketing NEVER responds !!!! so how do i do ??? I will show myself with my offer is that ??? !!!! #boycottbosch
