************ whom only repsond on hellopeter to look good

I finally received a response from Ula Wiggins last week Wednesday due to my hellopeter post whom responded to the incorrect query. Subsequently I have emailed her approximately 17 times to which I have received no response thereafter only read receipts. It seems they only reply on here as it is a public forum to look good. Why have I been invoiced 25 times and not the contracted 24 times for my handset installment (upgrade date 2 September 2015). Your accounts department has confirmed handsets are invoiced in arrears so why was i invoice for such in my invoice dated 3 Sept 2015 when the upgrade was only effected on 2 Sept 2015. Numerous calls and emails and Vodacom still continues to ignore me!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Please have a Managing Consultant contact me and NOT Ula Wiggins as customers dont like being ignored completely.
