No service every second week

Never in my life have I experience *********** and unreliable service like I did the last few months. First off a CellC agent contacted me about upgrading to a different data package. So instead of doing an upgrade, I now have a normal contract and TWO data packages that I have to pay. BUT, the worst part is that every second week I have to call them as my contract will be suspended for no reason at all. Then I have to spend half a day on a borrowed phone to get somebody to activate it again. Now I am unable to do anything as I don’t have another phone here, but I have to call them. And no, it is not an account issue as my account is paid by debit order every month.
