Cell c disgusting service and ******.

So for the past year I've been trying to get my Fibre line released from cellc, every call said it was being done yet nothing was done. Today I call and apparently I need to contact the legal department. Which I think is totally disgusting cause the first thing I asked for was a statement so that I knew my account was paid in full. Cellc trying to claim I owe them money when I don't.
