Thank you. Is it possible you to scan it and email it to me. I am happy to read it and see whether indeed, the payments are designed to go up and down.
Even if they are designed to go down as interest rates vary, if they haven't done it for a while and just decided to throw all the change on at one go, I think you have grounds for complaint.
I can tell you how to formulate the complaint and who to complain to , but I need to make sure first that y you have grounds for a complaint. I must admit that secured loans I have dealt with (other than first mortgages) have always been at a fixed rate of interest., it tends to be the higher amounts of borrowing which are on a variable rate , which is why I asked h how much the loan was for and over how many years. If you can confirm that you can scan the agreement, I can give you the email to send it to if you are unable to attach it.
Some users are able to attach documents and some are not , but the pages that I see different from yours so I do not know how it is done.
Don't worry about timescale because the thread remains open for a considerable time.
I am online and off-line all weekend and every day in the week in any event.
although I appreciate that you would like this sorted, it will not go away .
