Vodacom and MBD bullying me.

I write this review with disgust because I'm being harassed everyday by calls from MBD regarding the vodacom contract. i took a sim contract with vodacom whereby they were giving me data and minutes. In 2019 they stopped giving me those budles as per the agreement and i only noticed later as my account was no longer getting recharged. so after a few months i called them to explain that i'm busy paying for service that i'm not receiving. they promised to sort it out which they didn't. i receive invoices from Vodacom that says i owe 0.00 but MBD is harrasing me saying i owe 1 thousand rands something. i tried explaining to MBD that i can't pay for something i was not receiving but they keep on bullying me. i'm tired of this. account number of the sim in question is ***1-6 with contact number ***.
