Border Letter delay

I called Budget early this morning (2018/12/11) to request a border letter and after giving them all the relevant details, the agent promised that they would email it immediately. Two hours later, the letter still hadn't arrived and I therefore called them a second time and went through the same procedure.

An hour later, the letter still hadn't arrived and I then called a third time to request assistance. Its's now the end of the day and I still have not received the border letter and I still need to pass this on to the bank which is financing the car so they can send me all the relevant vehicle documents needed for crossing the border.

The delay from Budget is really inconvenient as I need to have obtained all documents before I go on leave by this Friday. This is meant to be a very quick, simple and straightforward process but Budget Insurance is turning it into a nightmare!!
