Vespa — Poor Service for a New Vehicle

Date of Incident - 10-July-2023
Date of Purchase - April 2023
I purchased my VESPA vehicle on the Month of April 2023 & gave for 1st Free service . After then, I keep on getting multiple complaints on this . Its purely based on service related & their team no proper response from Service manager side they seems to be harsh & rude if we ask for any queries. Now my problem is within 3months duration they are asking to replace the battery from a new vehicle saying that battery got drained out completely. After my investigation i found that my battery number inside the vehicle is different from the one which they entered in the system. Its purely a kind of cheating but they are not ready to disclose the information about the battery. Kindly take some action on this to get this issue resolved. This happened at JMB Motors, Ashok Pillar, Chennai
