Unsolicited marketing and email harvesting

I have received unsolicited marketing email from Mr Price Group for which I did NOT consent to.

I have requested for them to disclose where they obtained my personal information but they are ignoring my request.

Their privacy policy says to email their privacy at mrpg address but the mails are returned indicating that the address doesn't exist.

This is Very disappointing action and attitude from a public company.

I hope they can still afford legal protection after the lockdown for their ******* ******** activities.
