Call Centre Opt-out

Woolworths provides CCI Call Centre with contact details of Woolworths customers which I have no problem with, the issue I have is the CCI has no formal process of opting customers out and this feedback is never supp**** back to Woolworths.

Over the last year, CCI must have called me at least 5 times and each time I say please opt me out.

This is not an issue with the call centre agent but rather CCI and Woolworths.
