Vespa — delay in my bike repairs

I am writing in regards to my aprilia bike. I had taken it for my second servicing to k n mototech in south goa. I was informed that my bike wiring has a problem and i would have to keep my bike for the repairs. Since 16th august my bike is lying in the showroom. I need to keep calling them to ask about my bike for which i get only one response that the wiring is not yet reached. Very disappointed by the service and would never recommend anyone to go for aprilia bikes. They don't care for the customer. Hate it and i regret buying the bike.
