Bad service as usual

Since last night i was unable to use my bbm and whatsapp.... Why? My contact expires in april, but can upgrade from jan.... I got NO notification explaining why my service will be cut off on 31 jan, i upgraded today, but nobody at the branch could tell me why my bis was off!!!! They said that it was the blackberry server!!! Always quick to pass the buck!!! Now i have to pay extra to get this service until my next contract starts!!! UNACCEPTABLE!!! I keep asking myself why i stay with vodacom, by this contract will def be the last!!!
