im still waiting for my phone

i bought my phone samsung grand neo plus from this store after a few months it would not charge so i took it back as i still had time. the consultant told me that it would take approximately 2weeks. to get it fixed as it was only the charger pin that was the problem. im so angry at this moment because now it is 2months and a week since i dont have a cell phone. and every time when i go to the store they tell me that they will contact me. but they dont. i never thought this retail store was like this if only i knew i would have bought my phone else where. i am a dissatisfied customer.
