Most unprofessional service ever. Put my phone to fix the screen. They told me it needed 2 to 4 days max. Today is day 6. I called them several times.. They wouldn't answer the phone. However, the service UPSTAIRS answers but can't bother to go downstairs and talk to them. They said that there s only one guy working downstairs (on a Saturday) and that they don't have time to answer the phone. I arrive at 7:50 pm (the store closes at 8) and they are already closing the place. I try to enter, they say that all the employees are already gone.
Not to mention that when i handed in my phone.. The process took more than half an hour because the employees were too busy talking to their friends on the phone or talking about series.
I regret deciding to fix my phone there. People, go fix your phones at third party stores, im sure they take their jobs more seriously.
