MWEB VoIP, make sure you know the T&Cs !!

MWEB VoIP is not as cost effective as they would like you to believe. I have the basic package R69 which is good for my local calls but if I want to make an international call I have to buy international credits. You can only buy R99 and what you don't use will expire in 60 days. If you only make a few international calls a year this means each call will cost you R99. I don't understand why my money expires, in my view this is theft!
