Woolworths stop spamming me !

I'm constantly being spammed by Woolworths. If it is not telephone calls to offer me credit cards, it is reminders of how much i have available to spend on their card, to marketing emails.

I have tried to Opt of all this spam, by responding to messages, logging onto the website and even the old fashioned route to calling their office (needless to say that the number dialed, was not answered.)

Failure to address this directly with them, I'm using social media platform and if still not successfully, will most like have to resort to taking legal action.
