Quick to take slow to give

Vodacom is quick to suspend my line due to high billing but even after all the fights I still payed them R4734 and its been 4 days and still my phone is off I can use my data since this morning but unable to make or recieve calls I have phoned them and spoken to them the only thing they can do is log it on the network HOW LONG IS THAT GOING TO TAKE??? I am going to cansell thins contrac sooner that they think I am sorry to say but they are the most expencive and useless network in the world
