Savan Retailers Private Limited — Infinix phone is not charging

Hi There,
I purchased infinix phone from flipkart, it worked for 10 days...and then started problem. It's unable to charge.
I was trying to speak with your customer service but no one is responding... I went to Karimnagar service centre, they checked the phone and asking money for service. I showed them that it has 1 year warranty, but they denied to support.
Please help me, how my problem will solve
This is my contact number [protected]

I hope this support team will help out
