It started about 4 years ago. My phone rings and I see an unsaved number. The caller on the other end resorts to a familiarity tone, so I think it's a friendly person. He calls my name, middle-name and surname. He even quotes my address. The chat below is generally the conversation path:
(phone rings and I answer)
Bosshugo: Hello
SpamCaller: Hello, is this BossHugo(Bosshugo is not my real name)
Bosshugo: Yes, who is this please?
SpamCaller: O boi!!! How far na? Long time no see. How u dey?
Bosshugo: Fine, please who is this?
SpamCaller: Bosshugo, so you don't know who I am again. I am so disappointed in you. So, u forgot all about me, abi?
Bosshugo: So sorry, I lost my earlier phone. Please tell me who u are.
SpamCaller: My name is Jones Philips. We used to work together at Chevron. I am no longer with Chevron. I now work with Shell.
Bosshugofeeling confused, 'cos I have never worked with any oil company but plays along) O!!! How far na. Long time. U remembered me today.
SpamCaller: No mind me jare!!! I actually called u for an important business opportunity. Please call me back now.
Before I say anything, the spam caller hangs up.

Very recently, a a number kept on disturbing me. It seemed like an international number so the scammer felt I could be swayed. For security purposes, I am going to post the number here. +18088956707.
I think these scammers are able to get my exact details due to my job applications. Hence, I implore u all to help in fishing out these fraudsters and be more security conscious.
