Vodacom and Mondo in **** mode

Vodacom shared our details with Mondo who in turn (after investigating) had *****ulently upgraded a package we did not have even a sim card for. When contacting them they referred us to a company called Mondo. Mondo are useless communicators and the only resolution we got was it shouldn't have been done but nothing has changed. I am now of the opinion that they are quite happy to frustrate a customer until they just leave the problem and pay for services not rendered. Well done vodacom for frustrating me so much that I will change networks rather than have this happen again. Imagine if they could take accountability for their billing.
