when is the contract ending

. My contract expired end of March, I was then advised that I need to call and cancel the contract of which I did and I it was confirmed that my account is indeed cancelled. <br> <br> Last month when I received the statement I contacted virgin mobile and I was told that end of June is the last date that my account will be debited.<br> <br> However, today 14th July I received an account statement and my account to be debited with R322 end of July.<br> <br> When I called the customer service today I was shocked when the lady by the name of Portia informed me that the last day of debit will be end of July and that there is airtime loaded on my card.<br> <br> How is it possible? How can airtime be loaded against a cancelled contract. <br> <br> NB: I requested a cancellation letter, stating the contract period in writing and the last date of debit. I still haven't received the letter.<br> <br> I'm awaiting your response on the matter.<br>
