No service for months

A few months ago I app**** for fibre through cel c.

After the initial reply I heard nothing. My husband and I tried following up with no reply.

Eventually we sent a cancellation letter again with no reply.

We then app**** for fibre with a different provider only to be told cel c is still processing our order.

I want to cancel! Someone needs to confirm with me today. I absolutely do not want to sign up anyone who does not have the good manners to reply to my emails.
