Response to emails concering *****ing within the Campany

I received a call from on of my Forman saying he received a call from Vodacom requesting that he switch off his phone as they are busying doing a upgrade. He told the person on the line that he can't switch his phone off as no one told him about the upgrade, the person would have to speak to the Manager. He said when he got home from work his phone battery was dead. When he put his phone back on he could not make any calls. He contact me to let me know, I called my local Vodashop and was informed that a sim swop was done. Kim from the Vodashop (my correspondence lady) lodged a ticket of ***** as I never requested a sim swop. I was then informed the lock on the number had been lifted and that I had to contact ********** to pursue the ********** sim swop. I e-mailed POP on the 16th January and been requesting and update almost every week and they have not responded once to confirm that the matter is been investigated or anything. If this is what kind of Customer Service we are to expect Vodacom *****s from you, I say this cause the only way a sim swop could have been done is through a Vodacom employee as they had all our Company details and even my name and my boss. They managed to rack up a bill of over R6000 and we have already paid it as our account is on a debit order and if we don't they would just block our account and all our numbers would be lock. so we didn't have much of a chose. So people watch out and watch those value added bit they add on without you knowing. Very frustrated!!!!!!!!!!!!!!!!!!!!!!!!!
