this number calls 6-7 times a day and just hangs up. This has been going on for several weeks now. If I try and call back, it just hangs up on me. Most frustrating!

Caller: Zendesk

this company rings 5 times a day, despite being told we are not interested or the person they request is not available. they wont stop calling, this has been ongoing for weeks now

It is the same as the same people above. Constantly calls asking for the head of IT, several times day, everyday. I tell them no they say thanks and they call back again and again.

Caller: They don't say

Constantly calls to speak to head of I.T. Hangs up after being notified they have the wrong number. But it's ok, they call again the next day and the day after that etc.

Asked to speak with head of marketing 'for an update on SEO' - he hung up when put on hold
