Called at 8:30pm. My answering machine picked up and recorded a man's voice saying "Hello?" a couple of times, otherwise left no message. Whitepages reports it to be "voip neutral tandem" number. General consensus there was it's a telemarketing or spam call. Caller ID showed "customer service." If calls again, I'll block the number.
Called at dinner hour last night; left no message. If something that claims to be "Customer Service" can't even be bothered to leave a brief message as to why they're calling, I can't be bothered to let them ring through more than once. The Block List is filling fast...
