Both my husband phone and my phone (both Samsung S20s and both on O2 pay monthly), have the same issue.
I tried to call my husband's mobile last night from our home landline, which I do all the time, he has the number saved in his contacts, when I called, it rang once then an engaged tone started. When I looked this up on Goggle, it says this indicates the number calling has been blocked, we have also seen the number is then listed in his recent call log stating it is a 'blocked spam call'. I was able to call him on both Whatsapp and my mobile and he was able to call the landline from his mobile.
I tried his number again this morning, the same thing happened and I have also tried to call my mobile from the landline and the same thing has happened on my phone. We have definitely not added our home phone to any blocked number list.
Please help, totally confused?????????????????
