First of All cost is High. They dont provide original parts though they charge more than the dealer price. Still if you ignore to have the service at home and compromise with the quality other hand their service and Response is very poor.
They will make you wait for the whole day at home because they are not sure about the visiting time and in the end both gotango customer care number and technician number either switch off or will never receive your call. Pathetic Service. Never recommend anyone.
