Worst service ever.

Worst service provider ever ! Isi it possible for a company to have *********** employees in all their departments?.I missed a payment on on my contract in January which lead to my account being suspended.However I settled the account last month with the understanding that I will have my service reactivated.How wrong I was.First I've being sent from pillar to post for a simple.I tried calling the customer service department in order to have the SIM reactivated but then I'm redirected to collections department .I asked one the collections consultants why was been put through to collections department when I have settled my account and guess what he says "I don't know" .I then asked if him if wheter it was possible that the collections department might have barred the number and he said no the sim was active.Yesterday I got a statement that said I owed R539 which is 60 days overdue?What kind of ****ery is that?Cell C debited R500 on the 27th of last month and then R309 on the 28th and I paid an additional R40 .And yet everytime I try to call customer service I'm redirected to a collections department whose employees don't know their jobs.I need to have my SIM card reactivated.
