They won't understand the customer problem,they won't listen customer what he is saying,then how the customer will solve his problem,I went 2times to conquer service center in Ameerpet but still am facing battery problem with my iPhone 6.We are spending thousands of money to buy an iPhone,when we have an a problem they have to solve it,but they won't listen our problems,very very bad service by Ameerpet branch.
