Vodacom theft in open daylight

They have been *****ing our money from the last two weeks with data. I can't believe how all the data is being eaten up. Also I was subscribed to international calling rates plus but today I loaded R110 airtime. I made a few calls abroad and all my airtime was finished. I think it's because they have changed their number 111 to 135. So they disabled the international calling rates which is wrong because I didn't not choose to opt out. I'm extremely furious!!! Vodacom are *****ing our hard earned money unjustly like state capture!!!
