Incorrect Billing and No one is helping

Good Day <br> <br> I have paid my Credit Card in 2014. But in december 2014, i receive an invoice stating that i am owing you money. <br> <br> Please could you possibly have a look at this reference number<br> 1. D82FBF94<br> <br> I am requiring the following: <br> 1. All invoices from my Credit Card <br> 2. Why was i not contacted on my cell phone or my place of work <br> <br> I would like this to be sorted out quickly. <br> <br> Thanking you.
