Phone suspended without reason

My phone was suspended on 11 February 2016. After a few emails and phone calls we were told that there was a \pro rata invoice outstanding on the account for R188\" and that this had to be paid for reconnection to take place. <br> Upon requesting a copy of the invoice, we were told by Yolanda from Vodacom that she was driving and we had to wait for her office to send the invoice. At this point the phone cut out and we could not get hold of Yolanda again.<br> The amount was paid on Friday afternoon (12 February) and by Saturday morning the phone was reconnected again.<br> When following up on the outstanding invoice today, we discovered that the amount owing had nothing to do with my account with Vodacom, but related to a data contract taken out for someone else in the firm! When the amount for the data was not paid (we are still trying to find out where the invoices were sent), my line promptly got suspended!<br> I find this unacceptable that a company can suspend people's services at random."
