Best computer service and mobile signal boosterProfessional work

This guy called sampath kumar sold me a mobile booster but never showed up for installation. I paid him extra when compared to other providers because he said he will install it. he started to say things like not feeling well etc and now he stopped responding to my messages. stay away from him. refer the screenshot.EDIT after owner reply: From customer point of view, you need to either refund or arrange another person to install. You cannot say not feeling well for past 3 weeks. Anyways I will arrange another person to install and you keep enjoying the money. This is for other customers to be aware and be careful with you.
