Vespa — small bubbles which are beginning to appear on my scooter after the first service

We got the scooter on may. Its first service was done on june. After the first service small bubbles started appearing on the front body. We complained to the concerned retailer jovie motors but they are not taking responsibility for it. They are blaming us for the appearing of small bubbles on the front. I hope that u will deal with this problem and do what is necessary and preserve our faith and trust in this company and its products.
