Charged for sending 100's of additional SMSes

For the month of November 2014, I was incorrectly billed for a total of R 871.58 of Domestic SMSes.<br> <br> Upon viewing the itemised billing report (which consisted of 64 pages of SMSes), Vodacom's system had clearly incorrectly listed each SMS sent on 28/11/2014 multiple times!<br> <br> Aside from the fact that I know I didn't send multiple SMSes per minute to the same numbers repetitively, I also would've received complaints from at least one person had this been the case. Upon querying with some that I had sent the SMS to, they confirmed they did NOT receive it multiple times.<br> <br> I attempted to resolve this with Vodacom THREE times by logging service requests. The 1st case was closed without anyone contacting me!<br> <br> Only upon logging a 2nd case, the technical team \investigated"& then the agent told me the billing is correct"
