bad bussiness ethics

On the 3rd of january 2015, I went to have a sim swap at Telkom mobile maponya mall brach, the branch manager assisted me in this regard, however he then went and changed my tariff plan WITHOUT MY CONSENT, which I fully and instantly rejected, <br> <br> I've since made endless attempts to contact telkom mobile but no body at this company wants to take resposibility or even attempt to tnd to this matter, I am terribly at telkom and their system and how well they pass the buck, <br> <br> All the senior people at telkom are always unavailable, the'll always take your details and promise to get back to you, 2015 is now ending and not a single contact from telkom, really DISAPPOINTED!!!
