Vodafone India — vodafone is spamming me with calls

Address:

Mumbai City, Maharashtra, 400083

I was never a customer of vodafone.
I used idea for 6 years then i switched to jio about 4-5 months ago.
Latelly i’m getting calls from vodafone constanly & always from different numbers so i cant even block them.
Specifically they call me in the aftertoon time which is also my sleeping time.
It very hectic.
Its like a mental torture. I always pick calls even if its from unknown numbers so now it has become very problmatic for me.
I am not even a bit interested in vodafone india so stop calling me.
I hope you will resolve my issue asap.
Thank you.
