Unhappy customer

I had contract with cell company for 24 months and I told them that I do not want to renew my contract with them so I phoned them today after my wifi number was suspended and I was told that my cell number as well as my wifi are in areas of which is I understand but these guys at cell c don't have the decency to call and remind the customers about their payments but they are quick to suspend a loyal customer that has been with them for the period of 4years. I received another call today and she said that she is marking my account as unemployed after I have paid them every single month not even one month I have skipped. I am personally not happy with the cell c.
