I pressed 0 and spoke to someone. It is a Ted Cruz fundraiser, but I asked to be put on the do not call list. They are still calling repeatedly. Really irritating.
Irritating and illegal. Commercial fundraisers are obliged like telemarketers to obey your demand, which you stated correctly. Try drilling for the name and location of the call center, then repeat your order via Certified Mail along with a request for the company's no-call policy.
