outstanding account

I paid an amount of R1395 on 03 Sept 2015. The whole of sept i have been receiving sms's advising me to pay my account. Proof of payment was sent through twice. I have also communicated via email, via their call centre as well as in their Canal walk branch. Everytime I am advised that the records show the payment has been received but the collections department was not captured in on the payment. I have since paid my october account but noticed when I received my statement that the payment of 02 Sept is not reflected on it. I have again started receiving sms's advising me to pay my account. i have again sent though the proof of payments as well as an email but have receiving no response from Vodacom as yet. I do not have the time to waste on faxes, telephone calls, emails, visists to the branches etc. I wish somebody can sort out this problem. I have never had a problem with Vodacom before and hope that this is not the start of my problems with them.
