More calls than cover

Not happy with these people at all. Lack of understanding or unwillingness... Not really interested in knowing. I took out insurance with them and from day 1 I explained I am only available between 1 pm and 1 45 pm... That didn't sink in so I sent an email. No juice. They phone at least 10 x a day. And I keep on receiving emails. Ticket resolved. What ticket? The one that says you are very annoying. OK then why keep phoning. So I canceled my insurance with them. I was told someone else does that and I will get a mail. Day before yesterday. More ticket resolved mails no cancelation confirmation. And loads more phone calls when I said I can't answer. Now understand something here. Me or people like me don't live for phones and phone calls. I clearly stated which times I am available but disregard and some disrespect towards that one. Not a recommendable company unless u like spam mails and being bothered 10 times a day.... I see at the bottom I should put a reference number. All 100 of them?
