Vodacom is useless!!

I would like to share our experience with Vodacom since 1 December, my husband had a dual SIM card and since Vodacom discontinued this (without advising us) he can not make or receive any phone calls. They keep on escalating the problem since we contacted them and even advised that we do 2 sim swops. After 15 days, the problem still continues, without a notification or even a call (to my phone) to resolve the issue. We have been loyal customers for more than 20 years and it seems as if Vodacom could not care!! Considering going to a different provider.
