Afrihost's misleading message costing me money

Very upset with Afrihost, my fibre installation was install end May beginning June, anf did not want to activate it to avoid being billed for ADSL and Fibre, so I got the support call form Charles: I have had a look at your account and I am picking up that the Fibre connection is still pending on our system.

Kindly note that to avoid being billed twice you would need to cancel the ADSL line and data before the 23rd June 2018 this is only if your Fibre line is up and running.

So I activate my fibre and now I hear I have to pay for ADSL and fibre, they say they cannot deactivate fibre until end of the month so that I can first use my adsl. Beware of Afrihost's stories they tell you. So they not even willing to bill me pro rata for the ADSL subscription and data.
