Upgrad ****s

Mr meintjies thought he was upgrading same as my mother in law then saw it was new contract immediately sent it back since he has a cooling down period by law. He returned it within the right time margins he send it back but Vodacom is still deducting it they have all the paperwork to show they cancelled everything emails sent but nothing happens they posted on hallo Peter no one phoned them they are getting no reply what's so ever in this matter the guy Theo who helped my mother in law has also gone silent... He told me should I ever have a problem again to just contact him well I send 2 emails and never heard back they sent an email with all the documentation needed still no feed back. So why is this so hard for Vodacom to cancel someones contract when Vodacom is at fault. How many other people are struggling with same problem?? I mean just two in same town is already an indication of how many others there could be. This is unacceptable...!!!!!
