Bad service

Worst service since I became a customer! My mother is also a Cell C customer and she is experiencing problems and I am trying to help her solve it. I posted on their Facebook wall and they said I should send them her number but I am not using the Facebook app so also not messenger so I can't send them her number as inbox message so I asked for an email address to send it to them. I've been waiting 2 days for them to respond. After I asked for the email address they said - yes you can send us a inbox message???? Didn't you just read my comment asking for an email address because I don't want to post her number where the hole world can see it!!! We've been struggling for môre than a month trying to get het phone fixed but no one seems to want to help us that is why I turned to Facebook. But that didn't work either.
