All calls barred for over 3 days with no help!

My husband is without a phone for 3 days now. He has loaded on Hello Peter, called the call centre about 5 times and each time gets told they have no idea why all his incoming and outgoing calls are barred.<br> <br> He needs his phone for work and this is affecting his ability to do his job! We are absolutely furious. Each person tells him they will get back to him and find out what is wrong and yet still no calls 3 days later.<br> <br> We are so frustrated and on top of this he has only upgraded his contract with Vodacom 4 months ago and they have just increased his monthly bill for no reason. Apparently there is some small clause that allows this. I am horrified. We pay by debit order so all up to date.<br> <br> Can a senior manager please get onto this. I have put his ID and cell number below for you to contact him.
