Payment overdue

Dear Jet<br> <br> I hope that this email finds you well.<br> <br> I received a call this morning, stating that my account is overdue. I was surprised, because I make EFT payments every month and I never had this problem.<br> Now I'm asked to send through proof of payment to prove that I have made a payment.<br> What's the payment reference number for? Is it not for you to be able to allocate payments accordingly? <br> I'm not sending any proof of payment as this will cost me money to do so and hope that my credit standing with credit bureau will not be affected by this and should it be,I'm taking legal steps.<br> <br> Last year it was a magazine that I never agreed to have active on my account and when I asked that you refund all the money you billed me for the magazine, you refused and now you say I did not pay???.<br> <br> Please check your bank account before you say I did not pay.<br> <br> I'm very disappointed with your service I must say.<br> <br> Alfred
