call aborted

[Cybermoon50]

My elderly mother has a Doro 5516 mobile with O2 'pay as you go'. Recently, when she has tried to make a call, it either says something like 'call aborted' and she can't dial out, or it says 'call aborted' first and then the call is dialled anyway. She is in hospital and relies on her mobile to keep in touch with people. Does anyone know why this is happening? I would be grateful for any suggestions. Thanks.

When was the last time the number was topped up?

It might be worth contact customer services as well If you message O2 on Facebook (https://o2uk.co/O2CFB) , Twitter (https://o2uk.co/O2CTW) or Instagram (https://o2uk.co/O2CIG) , just to check nothing is amiss on the account
