Accounts department is making my life a misery

<p>Vodacom accounts department just took money from my account for a fixed top up contract, contract is supposed to be R70 and they went to my account and took over R2000 and on calling customer care they are telling me only accounts department can help me and i must call them back in the morning, now my concern is while they keep my money they are showing that i am not important and that they have total disregard for the error they just made not mentioning the incovenience, vodacom is making careless mistakes and they don't seem to care</p>
