Not getting response

My name is Lincoln Mokone.<br> <br> I emailed BMW contact centre to enquire if they received the manual payment of R120 I made on 10 of March 2015. I send an email 27 March 2015 and I still waiting to hear response from them. It is just confirming that the amount of 120 rands reflect on their system and it is not a difficult one to do. Reason I want confirmation is that I was given a new reference number and I linked the new reference number on my beneficiaries. There is a debit order in place, I just want to pay something extra every month so that I can finish this debt earlier.
