Bangalore Traffic Police — Wrong traffic violation fine

I have been fined on Oct 08 2020 for using mobile phone while driving. This I got to know today itself otherwise I would have raise concern earlier. Because of this pandemic situation, I was not in bangalore itself during that time. Then how can I violate a rule. I only drive my bike and nobody else has keys for it. I have a proof that I was in my hometown which is maharashtra during those days. If bangalore traffic police have any photo of me or my bike on that day then they can show it.
