has called about 5 times today--no one there

Calls a number of times a day. When I did answer it there was no response on the other end.

i keep geting calls, so annoying

When answer no one there.  This number very annoying.

received 2 calls from (204) 800-3254, caller id shows Winnipeg MB. No message.

Had five calls today. Took calls, I said nothing and just listened to see if someone would talk. No one did. No background noise just silence except that towards the end of one call I could hear a recorded voice say "goodbye". Calls started today 4 May. Just one thing to mention, immediately before the first of these calls there was an 0845 296??? number called which did not leave a message. Did this happen to anyone else ?
