Communication and problem solving

I have bought a VOIP international call top up on 6 February and until today, more that a month later, it has still not been activated. I called them a few times and every time I get promised that the matter will be resolved and someone would call me to con firm. All this has not happened. I also used up my local VOIP and had to top up because of the endless waiting when I call them. 30minutes and more is normal for them I regret that I chose MWEB as my service provider. They just don't communicate and make contacting them VERY difficult.
