Paid airtime not provided - 8ita

I have been buying R599 freeme boost monthly, which comes with 20gigs data and 1500 minutes to all networks amongst other things.

Free minutes aren't provided and I have made many enquiries to tge effect and I can't even get to lay a complaint, because they refuse to acknowledge my problem

Please help, my number is ********** 609
