I've been called by this number the past 3 nights. I didn't answer but if you call it back a voice mail plays that asks apologies for nobody answering the phone and asks you to leave a message.  No company name or contact person in the voice mail.

(234) 307-7990 .... continues to call everyday. Never left a message. I blocked their calls in Google Voice but the jerks still call everyday at noon. Goes right to spam thanks to Google voice blocking.
