It sounds as if you have a serious hardware problem. Calling and texting random numbers can mean your touch screen is failing but your problem may be bigger than that.

Contact Apple and arrange to have your phone evaluated. They can do some of the diagnostics remotely.

No, your phone its not being "hacked".

Please describe the symptoms you're having.

If someone tries to call you and they get a recording saying the number is not valid, either your line has been disconnected or they are dialing the wrong number.
