Overcharged AGAIN

Well what can I say Vodacom you have done it AGAIN!!! I have been trying for the past 3 days to speak to someone in accounts department after being told to dial *** and always land up in call centre. I have sent an email about my complaint and as usual no response!!! I have noticed that for 2 months in a row now that Vodacom have triple debited in September and then Double debited in October!!! Now once AGAIN I'm getting no response or no joy or any help to have my query and complaint resolved!!! Vodacom you seriously need to relook at how you run your business and how your customers are being treated. We are not just a number and no wonder you are losing customers!!! Now you left me no choice AGAIN but to lay a complaint in public because of your lack in communication and customer care!!! Can you now have decency to at least attempt the effort to resolve my accounts query!!!
