CELL C DISCUSS ME - TERRIBLE EXCUSES FOR PROBLEMS AND STILL NO RESOLVE- ONE MONTH LATER

So yesterday I received, once again a call from Cell C Customer Care, so this is now their newest excuse for my black data and normal data depleting at the same time. This guy tells me that my phone is updating when I am using my black box, really! Updating every time???? when on black?? does this make sense, I forwarded them two different days pictures when this was happening as proof. How ridiculous, why on earth will my phone do updates every-time I am on black?? I mean, I tried this a FEW TIMES, different days, and it was depleting normal as well as black data every time. And do I look stupid?? Obviously I was checking my phone, NO UPDATES WAS RUNNING, I even made sure NO ONE IN THE HOUSE WAS CONNECTED TO MY HOTSPOT!!! Honestly I don't know anymore, I got so furious with this ridiculous excuse, and if my phone is reflecting doing updates ON THEIR SYSTEM, NOT ON MY PHONE, while using black box only, then WHAT IS WRONG WITH THE BLACK SYSTEM???? Cause why would my phone start updating every time I am on black, and why is this not reflecting on my phone?? I told him that if Cell C want to continue with Black then surely they should have technicians to come and visit premises to sort out this type of issues, as they are seeing a complete different picture then me... on their system (ANOTHER PROBLEM). If a technician is right their with me he will be able to this with his own two eyes! I now am also considering sending a complaint to the broadcasting commission, cause Cell C is lying about BLACK it is NOT WORKING AT ALL, and they don't know what to do about this, (******** FALSE ADVERTISING) I think they can come and collect their BLACK BOX, pay me back the money and convert my BLACK DATA to normal data as this will be a lot more useful. Problem number 2, even if they do get a technician at my premises or be able to sort out this problem, how will I be able to test this? As the 7 day trial has expired!! It would seem absolutely ridiculous to purchase a package if you are not sure it will work. I HAVE TOLD THEM MANY TIMES, THE DATA'S NEEDS TO BE SPLIT, AS CURRENTLY THE TWO DATA'S REFLECTS AS ONE, THEY JUST AREN'T INVESTIGATING THIS!!!!! Why not contacting a qualified technician who knows about data to solve this??? Sick of their calls and no resolve!!!!!!!!!!!! and all the excuses!!!!!!!! ONE THING CELL C CAN DO GOOD IS TO APOLOGIES as if this is now going to make everything better!!
