No Data Network

I have a 24 month Vodacom contract with 5gig recurring VAS. the reason for the 5gig recurring VAS is because i use data more than i use voice. this started last week Tuesday when i realized i had no data network and used my other phone to check on twitter if there are any reported problem, and low and behold there were number of complaints and Vodacom apologies for the loss of data network. then on the Thursday evening the same thing happened, i then called, the call center requesting an explanation to the recent loss of data issues and when they are foresseing permanent resolution, i was informed that they are aware of the issues and was given a work around, the lady refused to log my call. On Saturday i was off for most of the day only realized the next day when i started receiving my whatsapp messages, i wasn't even aware i was off. This morning again, i'm unable to connect to data network. i called the call center and i was told that they will reset my network connection and i must try again after some time. i still don't have network connection. i would like to have my contract cancelled so i can move on to another network, i cannot afford the downtime especially with no communication on resolution.
