Unacceptable trading hours

I have a cellphone on a business contract which was ****** at +/- 18.05 on Friday 15/01/2016. I tried to report same to Vodacom at 19.45 using the help line ***, only to be advised when I managed to get hold of someone on another number that the corporate department is closed after hours and I would have to wait till Monday morning notwithstanding the urgency to block the sim and blacklist the phone. After numerous attempts to speak to a representative, someone called me back and was supposed to send the blacklist form with a case no. and a sms to report same to SAP, still waiting.<br> TOTALLY UNACCEPTALE SERVICE
