Vodafone India — vodafone charged rs 448 for a call which i haven't made on 51717

I am a loyal customer of vodafone for last the last apx 8 years, having 7 numbers on my name under corporate scheme. Vodafone charged on my one of the 7 numbers rs 448 in my september 2017 bill for a single call dated 15.09.2017 for 32 minutes on 51717 which i never made. It is not good on the part of such a reputed company like vodafone to penalize their customers. I lodged a complaint with vodafone.. What they are not ready accept their mistake... I once again request to vodafone to rectify above error in billing of september 2019
