Around three weeks ago I had an upgrade to Full Fibre with Digital Voice. Ever since then I've been receiving No Number calls twice every hour. The phone doesn't actually ring but shows as a no number missed call.
The calls occurred at three minutes and thirtrythree minutes past the hour. But recently changed to four minutes and thirtyfour minutes pas the hour, so 13:04 and 13:34 for example.
I believe it's coming from some automated system on TalkTalk's end, testing the line for example.
I have reported it to to TalkTalk three weeks ago and the operator at the time agreed that it does seem to be the case of a phone line test from them. I've since contacted TalkTalk several times about this for an update but they aren't getting back to me at all. Please can someone look into this for me.
