Poor service and product quality

I have been waiting for someone to check my speeds on my fibre. I placed and order for a 25 25 line with cell c. This took a month to fix. They then took a further week to set up the router only when a technician was assigned to it. I was also told I would be receiving a cell c black box with 3 months free black usage. It's been 3 months of me calling, mailing and sending messages on Facebook to cell c yet no one cares to help. It's always, "we're looking into it" or "we've done a remote test and everything looks fine" they charged me for a 25 25 line yet the speed has never gone above 9mbps. They then told me I need to take screenshots at different times during the day, which I did. It has been so painful to be with cell c. They then also said they charged me for a few days even though i didn't have any internet. I just want my Cell C black box and my speeds to be what I've paid you for! Else refund me and I'll find another ISP. Everyone seems to be raving about supersonic at the moment
