No claim payment for 6 months!

I wish I could give no stars. I've been trying to claim since November 2019, yes, you read that right. Once someone phoned me in March, March! stating that they need this and that and that. I expressed my frustration asking why they are only asking for this now but she couldn't give me an answer. Anyway, I received an email early April saying that I would get my claim but has since been asked again for the same documents. And since then, again for the same documents. I cannot believe a healthcare provider can be this shocking in service. I really do suggest everyone to move to another provider asap, I will, soon. And.... I will take this to the ombudsman.
