Back and Forth emails

I had a Capitec bank account in which my Salary used to be transferred into. I then changed banks for a very good reason such as the one im about to mention, my current bank is Nedbank very efficient and better than expected. I emailed Capitec Forex a week ago regarding Forex that will transferred into my bank account as reimbur*****t for my medical aid. I had then explained that my contact details had changed and I REFUSE to go into a Capitec Bank just to update a cell number. Anyway, I get sent a looooong form 8 pages to tick and do whatever. Then I get a email saying I must fill out senders details. Really now???? This is money owed to me that you want me to update 8 pages of a form???? This is the reason I dont bank with Capitec any longer they are slap and I will be closing the account for good once I get my medical aid reimbur*****t,
