Voltas — Voltas ac

Our ac is not working from last 10days. ac isn’t doing cooling . i have two ac of voltas. first one is a 2 old and another one in 3 year old. Both the ac has same issue. I registered my complaint on 16 april. And today is 24april. All the customer care number are busy and I don’t know what to do. my personal suggestion is please do not buy voltas products it’s quality and service are very very poor. i know daikin o general hitachi are expensive but believe me Their service is amazing. The ac which is 2 year old has facing this problem second time. now you understand how much the voltas product is reliable
