BAD FRODULENT SALES FROM VODACOM

I am very upset and disappointed with the service I am getting after taking a cellphone contract with home mark and Vodacom I took a cellphone I was told about the montly fee was supposed to be 374 which more money is being deducted from my account ,they told me I was going to get more gigs on the router but now everything is a lie I keep getting different consultants calling me about this phone and giving me a different story ,calling Vodacom is useless and they keep giving me the home mark number which isn't going through, please assist me am really not happy with this service and I cant keep reversing money from my account as this will affect my score .
