Combox Pro cancellation

I am being charged for a Combox Pro subscription from Swisscom, although I have never requested this service.

Does anyone know how I can turn this Combox Pro off?

Many thanks in advance.

@TerryRalphs where do you use the Combox Pro service on Cellphone or on Fixnet?

@TerryRalphs You can let Combox Pro be deleted via the Hotline 0800 800800

Many thanks for your reply.

I have tried that and nothing happened, even though they said that they had cancelled it. I will try again.

@TerryRalphs If there are still difficulties, I would politely insist on speaking to 2nd level support. Good luck

Thanks will do, I didn't realise that there was a second level of support.
all the best
