Non fulfillment of service

Hello, I have been facing an issue. I hired a photographer for photoshoot during wedding. there was a verbal agreement regarding the payment and amount was decided as such. The concerned photographer didnt attend the ladies sangeet and asked me to click the pics on cell that he promised he will make. also there were videos which I shot myself and gave him after to edit. on the day of wedding he arrived late than the time that was given to him for the departure of barat and thus we got late. Also, we paid him an advance as required by him and he promised to deliver soon. after 4 months of making excuses and not picking up calls, i had to go to his place where he demanded more money than agreed. i refused to pay and now after a few weeks he sent me a legal notice accusing me of cheating.
