Cancellation reversal

I cancelled my Telkom ADSL on 23/03/2020 due to poor service. Now my "new" service provider is unable to do new installations during lockdown period. I tried to cancel my request to cancel with Telkom. I was advised that once cancellation is placed on system, it can't be reversed. Surely in these uncertain times, they would consider that people are working from home and will need an internet connection.
