Are you also annoyed Just like me??
I know you are gettings lots of phone calls and disturb your privacy from these so-called telecom companies. Actually, they are making money while you are listening to those lame Advertisement from Insurance, Offers, Plans, Credit Card etc. You can use Do Not Disturb features to avoid those calls.
Your Numbers are selling to most of the Advertisement companies after that they start calling you for numerous things.
I was also Victim of this kind of Shit. However, I have become smarter and used DND (Do Not Disturb).
