Cancellation of debit order

Good day<br> <br> My 15 year contract with Vodacom ended 31 August 2015, and my number was ported to a different service provider.<br> <br> Vodacom then debited my account in September for R2018.63. I have received no statement for this amount due.<br> <br> I have spoken to Phumzile in your collection department and was advised that my number and debit order details has been removed from the system effective 5 October 2015 ( ref 005G-G68E)<br> <br> Yet again I have received an email advising of a debit order that will take please.<br> <br> It is impossible that my account is R2018.63, I have NEVER had such a high account due in my 15 years subscription, <br> <br> Please can someone get back to me in order to resolve this issue <br> <br> Kind Regards<br> Yolandi <br> <br> <br>
