How to cancel appointment at my home address with technician (not needed any more)

Hi,

I had connectivity issues yesterday and scheduled a service appointment at my home. However, today the internet is back again and we don't need the service appointment any more.

I tried to cancel through the app, but there is only the option to reschedule, not to cancel. I cannot find that option online in my account page either.

Can you please help me cancel?

Thanks
