Disappointed is an understatement

I have changed my Vodafone contract to prepaid with much trouble about a month ago. Struggled for more than an half an hour to get it done,as they just want you to take another contract. It was so aggravating and exhaisting. It wastes your time,where they can just do as requested. So now a month later I get the message that my contract has ended,so has my notifications aswell. You habe to phone to activate it again. Probably just another **** to try and convince you to get another contract!!! Oh Vodacom knows how to get your blood boiling! Absolutely disappointed!
