Have been receiving calls from this number sequence for last 3 weeks - daily. From other comments I can see they are a super survey call centre who ask extremely intrusive questions. Do not answer their calls, phone them back and certainly do not disclose or confirm personal information. Numbers used so far are 0480 012 403, 438, 391, 365, 412, 366, 446, 432. I normally don't answer numbers not in my contacts but these people are infuriating me so much I am now answering not speaking and let them hang up.
