Lenovo — cheated by authorised lenovo mobile service centre @ thrissur, kerala

Address:

Thrissur, Kerala

My mobile lenovo vibe k5 note had complaint of delayed charging. It was taking long time to charge and not detected in any laptops when connected.
I contacted near by authorised mobile service centre at thrissur, kerala.
They said, their is problem with sub - board and need to change it. I said ok, and changed. They charged rs. 1400 for it. After 10days of repair again the same complaint has come, that is of charging issue. I'm cheated by service & charged simply for improperly done service.
I'm fed up with company mobile, service centre service. Full of cheating.
I want to get it repaired immediately and i won't pay single rupee back otherwise i'l go to consumer court
