Who called from 9788810972

Calls but never leaves message

no message just annoying calls

Caller ID shows as "Customer Servic" (sic), didn't leave a message.

Recording re: electric bill reduction (scam) - comes up as "Customer Servic" on caller ID.  We are on the do not call list.  We have received this same recording from other numbers in the past, so blocking their number doesn't seem to help - they just use another :-(

Just recieved a call from customer service....I did not pick up, no message left.
I get all sorts of useless calls like this. There's no end to it.
