Misinformation given by sales agent and then being treated very poorly for doing as we were informed.

I did an online quote and got a call back. At the end of the phone call the agent ask for banking details to finalize the quote. I said no and was not comfortable, the agent continued to pester me for it. The agent said that I must remember that I can cancel anytime before the first payment, that I must give my banking details to get the discounted price that he quoted me because if I do not and I phone back later the discount will not apply. I must just let him know before payment date and he will cancel immediatly. Only after the third call I received did I say yes and give my details. I asked again to make sure that I can cancell before payment, he confirmed that I can. When I now made a decision to not go forward with the quote and emailed the agent as he instructed me to do. I was ghosted. I phoned Virseker to cancel and was mistreated. After long minutes on the phone to explain myself like a child, I could not continue. I asked my husband to sort it out. So as per that conversation he informed my husband that I must remember that there are recorded conversation where I agreed to give my details and that I can not just cancel. The more my husband explained that we were told that we could do excatly that, cancel before date of payment, the more the agent argued with my husband to not cancel. It was not a pleseant conversation. We were misinformed by the professional. I am very upset that we had to be mistreated because we did as the agents said to do. Please look into your training of agents and maby don't mistreat the client when I just want to do what I was told a can do without problems.
