Cell C SP - April 2019 Statement - Account # ********** 61. 2 years ago I took out a contract on a router. 10gb day and 10gb night at R250 or round about there. (Must find my contract). A few months later my payments started going up. I was told to cap it at R500. Anyway long story short. I kept getting charged R500 each month even on months that I did not use the router at all. Many attempts to query this with various staff at cell c has just resulted in frustration. So now I have been handed over for R1999. as I stopped the debit orders. Really? I think cell c owe me
