Can’t make or receive calls

[Carter1]

My phone is not allowing me to answer or receive calls. Have checked setting and microphone and all seems ok

Try rebooting your phone @Carter1

Have you missed a payment?

Have you checked network status? https://status.o2.co.uk/ 

What phone is it and where did you buy it?

Hi

I have not missed a payment
Have checked network status and there are no problems there
Bought my iPhone from an o2 shop

You need to call O2 then choose any of the options, fraud etc
Everything is taking longer due to the lockdown. Call centres and social distancing means limited staff to handle all the queries. Patience needed I'm afraid.
