Lloyd — AC not installed after a week of purchase

It's been a week that I have bought 2 AC's from Lloyd's, unfortunately after registering to fix it no one has turned up. The AC's are kept like a show piece without fixing. What is the use of buying these AC's? I have 3 kids and we still suffering to sleep in this summer inspite of purchasing the AC's. Totally dissatisfied and disappointed with your so called service.

Your person will never come to fix it. Please return my money or I will have to sue your company in cheating and fraud. Please don't make me do it. Have some humanity.
