How to turn off voicemail

[Danoldson6]

Thanks for info I’ve now managed to switch it off I’m getting a lot of sales calls from some firms they phone from a mobile number and if voicemail answers I get charged which is costing me money which I obviously don’t want

How do I turn voicemail off please?
