Terrible customer service

I am really disappointed in your credit life department, your assessors gave me forms to get filled by my employer and Doctor which was filled in and sent in July but just last week they send me the very same form and ask me to ask my doctor and employers to enter the forms again, this is exactly the same form and they want them refilled in order to know why I am booked off sick, the form I sent them required me to go to my doctor set an appointment and be evaluated for her to give you guys the necessary and most accurate state of my condition currently but now you telling me to resend those exact same forms for these people to refill both parties gave you contact details so that should you need any further confirmation you can contact them, the lawyers you handed my account over to is also asking me how far my application is why am I doing your job for you? Do the necessary investigations in order to get the information you need, I cannot be expected to resend the exact same form to people who are working because you need my diagnosis to continue with my claim, why are you also not updating the lawyers as to how far the process is why do I have to make calls left right and center to get information for lawyers you hired to get a case done, I am already going through a lot I do not need this right now. You are making my life difficult, it takes ages to assess my claim then when you do respond I am told about refilling an already filled in form, what annoys me is that it is THE EXACT same form, word for word.. I am really upset at this point and I am not physically and mentally healthy right now and you are just making matters worse for me as a client. I am trying my best here it would be really nice if you did the same
