Cartrack wants me to pay my premium twice

I've just received your sms stating that my debit order has returned unpaid and M in default.I want to categorically state that the debit order went through on Saturday, the 14th of October, 2017 (No need to furnish you a proof, do a thorough investigation on your side). The said amount was debited on this date. I don't know, maybe things have changed and M expected to double the premium every month. I'll go to my bank and reverse the debit order and deposit the money directly to your account. Could you please give me your account details and also indicate the reference number that I should use. Unfortunately I can't use the requested method of payment indicated in the sms because I don't have a credit card. M putting a humble request to you to stop debiting my account as from this month. I will pay my premium throught EFT.
