The worst telcom service provider

I have a contract with vodacom for over a year. When i first took out the contact they told i was on per second billing. After 5 months i get a call saying if i want to upgrade my contact to per second billing so i told them but thats what i am on. Anyway i agreed and my contract then went up. since i got this Top up contact the R230 airtime doesnt last even 2 days. No calls are made and i swicth off my data has i have wifi at home and work. I have complained numerous times. Vodacom is just a *****. Cant wait till this contract is over so i can move to another service provider.
