Disclosure Of POPIA

A call agent from zone fitness somehow got hole of my friend's number , called her an then gave out my details an information without my constant , I gave them all my contact details which they could get hold of me but instead they contacted someone else without my permission , the call agent didn't give her name to me when I asked , I tried calling back but wasn't assisted ...I'm so angry becoz this is a violation of my privacy an POPIA!!!!

I emailed them an they never responded , they so quick to call me an email me but now they can't evens read my emails .
