Beware of Infinite Debt Solutions!!

I received a call from this company telling me I was being overcharged. I immediately dropped the call. But immediately afterwards, I received an sms from them saying I "gave consent to request my credit report". Judging from the reviews on this platform, it is clear that I am one of many if their victims. Where did they get my cellphone number from? They even have my ID number. These people are ****mers and they need to be stopped. Who gave them permission to invade my privacy?
