BT can support customers who are having difficulties caused by living with conditions across the mental health spectrum, including dementia, learning difficulties and Obsessive Compulsive Disorders (OCD). Network Controlled Calling or 123 & 118 call barring are a couple of options which can help to limit calls to premium rated numbers and lots of repeat calls, preventing costly bills being generated.
