RCS delay tactics.

I app**** 2 months ago for credit cover which I pay for every month. RCS then contacted me so late for more documentation that the first of the 3 months statements that I sent became obsolete and they asked for another statement. I again sent all the documents that were requested and got an automated response. Then I get another email telling me that I needed to make a completely new application. So I did. Then I get a new email telling me I need even more documents. In the meantime 2 payments have failed and I am now behind on my payments due to how slow they are. Now I’m getting phone calls every 2 to three days asking for payments that I don’t have the money for and I’m not getting any responses as the where my latest application is that I sent in 2 weeks ago. These appear to be delaying tactics and I am starting a formal complaint with the ombudsman. I paid for the cover, so why am I being sidelined like this?
