[Resolved]  Motorola — service center made wrong job card

I went to tilak nagar motorola service center and they checked my and told me that we don't handle warranty phone kindly go to another service center, when i went to the rohini service center they said the job card is updated as liquid damage so the warranty has become void.
My phone has chargng issue, the man who opened my phone said the motherboard needs to be replaced and nothing else
Just because of the false job card updated by tilak nagar service center the phone's warranty is showing void.
The customer care executive are not helping me resolve the issue.
What to do?
