CELL C Fibre disaster

I have been with Iconnect for my Fiber, I paid my debit order every month without fail. all of a sudden CELL C takes over without contacting me at all disconnecting my fiber without contacting me, and telling me I owe them over R5000 in service. And that its going to take 48 hours for them to contact me This is disgusting behavior this is not customer service. at least have the decency to liaise with your customers who don’t know you exist.
