Never seen such a unprofessional & irresponsible behaviour by AEI person Manjeet Kaushik who owns the business. He doesn't know hoe to behave with customers and uses foul & goons languages. He gives just disgusting after Service and support. Your life become nightmare as No support & services rendered by AEI once you purchase the products from them. They're just money maker and false promiser. Never ever buy any product from AEI company Gurgaon otherwise you'll repent later. He says you've not bought him personally and he is not bound to take your calls & gives services.
