Vodafone — Flawed bill saying international sms were sent

Hello,
I need to urgently report this issue against vodafone india. My wife's vodafone number got an unusual billing of inr 930/- when her usual bill amount is inr 470/- when i called up vodafone india to register a complaint against this, they said the itemised bill is not yet generated and they cannot help me until they see the bill. I called back after two weeks and they took down the complain. Today i was notified that there is no issue in the billing and they cannot help me in rectifying this.

When i checked the itemised bill myself i was shocked to see that they have billed me for 79 international sms sent on one single date 27th august 2020 between 12pm to 5pm.

All of these were different uk numbers starting with 44703 and some to turkey numbers. I can say this for sure that we do not know anyone in these countries and we have never sent these sms.

Is this is a kind of a scam? I need urgent assistance for this.
