Vodacom contract false information

would like to report Vodacom for false adverti*****ts together with Elite mobile .I signed up a contract telephonically for a Laptop and upon delivery 7 days after my account was debited for a connection fee and prorata amount which was not communicated by their agent Elite mobile .Secondly i was told that i will only start paying for the contract end of July to my surprise my account was debited in June.I called vodacom several times and spoke to their call center agents and the final agent i spoke to from their after sales department ,says there is nothing they can do.This is soley unfair as this was not in my budget.Vodacom should credit my amount back and they can start debiting the amount in July.
