Cell Prank Calls

So i just got a call from some **** at Cell C who giggled while trying to do a prank call. Does CELL C condone this type of behavior and customer service to loyal hard working cell c subscribers. This after i have recently taken 2 new Cell C contract to support the struggling Cell C network. Its disappointing as i answered the cell c call with great professionalism only to get giggled at as if i have time for prank calls. If cell C can contact me i can help them with the time of the call so they can investigate. Please look into this as this could cripple the subscriber base. I read a lot and I know Cell C has been struggling so they got acquired by Blue Label Telecoms. Lets not waste an opportunity to grow as a network by employing consultant that use their time messing with subscribers.
