Billed after numerous calls to cancel service

<p>I have 2 top up contracts with Vodacom and purchase data bundles on the first of each month. I think that its a complete ******* for Vodacom for you to allow that you can add monthly subscription charges to your account by using the ussd menus. on more than one occasion myself or my daughter have selected the wrong option and instead of buying a once off bundle has purchased recurring bundles. each time I have immediately called Vodacom and to my horror there is no way they can reverse the mistake. at the beginning of November I once again selected the wrong option and a recurring bundle was activated. I then immediately called to cancel. I was promised that it was cancelled. I called back in mid November to cancel and I was again promised it would be cancelled. I logged onto my tablet on the 16 December and noticed that another gig was added which meant my recurring bundle was not cancelled after my numerous calls to cancel. you have now billed me for it. I want my money back in my account immediately. you have no right to debit my account for transactions that I have not authorised and cancelled on numerous occassions.I am cancelling both my contracts after 20 years of being a loyal customer. I am absolutely disgusted.</p> <p> </p>
