Payment not reflected on account

I made a payment on 1 December 2015 on my account. I unfortunately added an extra zero to the account number. I went to our local branch with proof of payment on 9 December because Vodacom suspended my service, provide proof of payment and the service was restored. Thanks. When I received my account the payment did not reflected. My services was suspended again! I paid the amount again plus the amount for January because I needed my internet to solve my problem. The staff at Bela Mall gave me a email address to submit the proof of payment again. I have done that twice without any response form Vodacom. Please can this be rectified.
