Cold callers. Talked a load of rubbish. who actually used the services of strangers who randomly phone a business? i am astonished that employing these people is financially worthwhile.

Robocallers, rude

Robocallers that ignore do not call list. Which is illegal. Do not do business with criminals.

Horrible spammers. They've been calling me every other day for the past two months, offering unwanted web-services. They do not respect requests to unsubscribe from their shady marketing list and will spam non-stop.
