Do not want to log a query.

All of the sudden Vodacom increase my monthly fee. I have a 24 month contract with a amount the we have agree on upfront. You can not just increase as you want. I will not pay it. I made a call to the Call Centre, the second time spoke to Ruben and he tell me that he cannot will not log a query? This will be my last contract with vodacom. Vodacom score 0 out of 10 from me.
