They did the same to me, only I'd paid even more when they left out my (blue in this case) wallet and just sent me a sheaf of papers. My first UK licence too, so it confused me.
Then they took 3 weeks to even bother to look at my renewal, I had to go down in the end to pick it up as it is my livelihood, and charged me over £100 for that dreadful service! How can it take 3 weeks to look up details of my existing licence and print them out on new sheets of paper, and how can it cost so much (albeit with a new plastic wallet)? This should be a two-day turnaround, with some delay in busy periods, not a two-week turnaround with even more delay in busy periods. It should cost around £10-20 to administer. It is a rip off.
