The telephone number 01755 175238 is being used as part of a scam targeting BT customers. If you receive a call from this number then do not answer. If you have already answered then hang up immediately.
These types of scams involve a call from scammers pretending to work for BT. They will then suggest there is a problem with your internet connection or router. They will then ask to get remote access to your computer so they can sort it out. In fact any security access you grant them will be used for phishing. Anything they find will put you at risk of fraud.
Do not answer any calls from 01755 157238. If they leave a message for you then don’t phone them back.
