incorrect info given and NO CUSTOMER SERVICE

I have had nothing but bad attitudes and terrible service from Vodacom, they called me to sell a data contract and was given incorrect information, all lies, I called to cancel they have the nerve to tell me they will debit my bank account and I MUST WAIT 14 DAYS FOR A REFUND, after they sold me ******* and I called 24hrs after to cancel, the teamleaders in aftersales is rude and have no sense of customer service, I am still waiting for a manager to call me back because they always in meetings I don't know to discuss what!!!!!!
