Harassment via sms for someone else's account!!!

Getting sms's for someone else's account. I am being harassed by SABC TV Licence via sms. I have contacted them on every single email and telephone number possible. I AM NOT NAIDOO!!!! THIS PERSON GAVE YOU THE WRONG TELEPHONE NUMBER!!!

Account Holder: NAIDOO Account: 112 876 28

PLEASE UPDATE YOUR RECORDS!!

The telephone number you are using is NOT for the account holder, it's for a totally unrelated individual. I have contacted the SABC TV Licence offices in every way possible!!! Telling you that your details are incorrect but I have been ignored.

Can someone just please do one thing for the salary they're being paid. Fix a telephone number on an account! That is it!
