Nice Scooty, but pathetic after sales services

I bought Suzuki Lets last year and writing this review after one year of use. In May 2015, the battery of my scooty was not working properly, so I called the service center and was advised to bring battery there. I did the same, but the person there asked me to talk to another person. The second person told me that the battery will be replaced within 7 days and also told me that I can check the status over the phone (
which was not working).

Battery Submitted on 2 May 2015.
Called them on 5 May 2015: No response from their end.
Called again on 6 May 2015: Same result, no one picked the call.
Called on 8 May 2015: Again no positive reply.

When I called on 10 May 2015, there was a lady who picked the call kept me telling that she will herself call me. I waited till 15 May, but did not receive any call from that lady. So finally on 16 May I reached there to check what exactly is going on. When I reached there, I get the same reply that they will call me by them self. After waiting for 15 more days, I finally get the call saying I can pick the battery from their service center.

Coming to the scooty, it has a nice ride quality and brings out good mileage. Apart from that service center issue, I never had any trouble with the scooty. I would like to advice Suzuki that to be successful in the market, they need to offer nice after sales services.
