Contract dispute

<p>Last year end of November I took a contract with Vodacom of a tablet paying R99 p/m over the phone. The agreement was that the first deduction will be January. But Vodacom didn't honour their word instead they made three deductions from my account and I reversed them because it wasn't our agreement. January I received a statement that I owe Vodacom R310.05 I wasn't happy with that because I don't know where they got that amount. Now this month I received another statement saying I owe R676.55. I'm not happy with their service at all and now they have been a huge inconvenience to me and I want this matter resolved ASAP! My reference number is I ********** .</p>
