Unacceptable service Afrihost

We have tried to cancel my Afrihost account since 1Jule with big promises to have a time to help us offered month free just to experience the same poor connection with being forced to pay for a another month. After paying and waiting for another month to cancel now we can't move to a new service provider because Afrihost refuses to remove there line. Now we stuck without internet for 7 days already after following their procedure and just to support or effort to have this resolved.
