Elica — Product service

I bough elica chimney from amazon. It’s just 3 months and now i facing oil leakage issue in that. I called customer care for that and raised a complaint there on 30 September 2021 and today is 07 October but till that time no visit or call from technician and I’m calling daily to customer care of elica. They daily told me that our technician will visit in 24 hours but it’s more than 6 days no one visited. My elica complaint number - CRM ID- 99_2076253
