guys who changed their legal name on their DVLA license, is this normal?

i was trying to change my name to my new, legal preferred name, but they always declined my application and sent it back. did it 3 times, and did many mistakes to the point where i had to keep going back to the post office. i thought it would be a good idea to apply for a new provisional license overall since it would make it easier for me and won’t have to write on a paper — but then these mfs decided to send me back this and i needed to send it back within 21 days.

DVLA, what the actual hell.

the questions they are giving me are those i already answered online, WHY in god’s name do they want me to write it in a damn paper even though I already applied for it??? now i have to pay extra in shipping fees and this feels like a waste of money!!!

please tell me that i’m not the only person this has happened to. is this meant to happen??? i thought if you apply (especially if you provided a passport number) then they just give you the license and done! am i crazy for freaking out? am i the bad one here? what should i do?
