The kind man offered to help me solve this problem. I told him that would be great but I have a hearing problem. After 20 minutes of him shouting instructions at me he was starting to get a bit irritated. He then asked for my internet password. I spelled it out for him (EMMAFUGWET). I told him to yell it back to me three times which he did. The call then ended abruptly."
