Dololo response

Ok so I've been trying to call and I've sent a inquiry but dololo response. Can you please be as active regarding my problem as you are in taking my money. My app doesn't work, I think the tracker is outdated as i was sold a new contract with perks. I was told I don't need to fit in a new tracker. Then I got smss saying I have an appointment. Do can someone please tell me what's happening? Am I now paying for nothing? Plus I'm in breach of my insurance contract should something happen i won't be compensated. I hope I'll get a response now.
