Bad service

On the 5 May i took out a contract at Vodacom Horizon view with Sipho. I was told that the activation fee will be R121.00 debited two days after activation. I made provision for that amount but my account was debited R191.00 which was over the amout i had in my bank account and the debit order was returned unpaid and i was charged R150 by my bank and as the result I told Vodacom to cancel my contract . I was told to contact <br> customer care which i did on the 14 May 2015 and i have ref numbers of the communication. <br> <br> To date this complain is not resolved and I send emails to customer care with no response from Vodacom.
