I called back number (02) 8019 6351 company name is macquarie banks and spoke to card services department.

macquarie bank (02) 8019 6351 & (03) 9012 3367 ring about 5 times a day but never speak too you, they just keep hanging up - pain in the necks

They keep ringing but leave no message

Had a series of calls with similar prefix on mobile. No message left on voicemail. I have blocked the calls. 11 calls in the past few days from 80196351, (02) 8019 6351, (02) 8986 8351, (02) 8019 1535, (02) 8094 6021. and variations with 61 prefix

When I answer these calls on both home and mobile she asks for my husband then hangs up when I say he isn't here
