Service sucks

I am struggling in just getting a bank verification form completed. 1st the consultant does not inform me to complete the details that a normal bank would complete. When I call back to verify the turnaround time the 2nd consultant says I need to fill in all the details a d they will just stamp and sign..that was on Monday 27 Feb 2023 started at 9am continued during the day until it was corrected and completed. Today 1 March 2023 having made how many calls, had to resend it again at 15:49 now it's being escalated as the 48 have passed. Is it really that difficult to sign and stamp a document that cannot have any implications for the bank should it be incorrect as I personally completed it with my details.
