Citroen dealer useless

I begrudgingly ordered a replacement key fob with remote from a North Wales main dealer at a total cost of around £95. They kindly phoned me a day later to say it was now in stock. I then double-checked that they had the code and the key to complete the job of programming the new key in. They confirmed they did and I booked the car in. I called today as arranged but was told they were busy so I'd have to wait half an hour. Not a problem. I walked around town for 30 minutes then returned. I was then told they did not have the transponder code! Not a word of apology. I had therefore wasted two hours in all. This should have been the simplest of operations for a main dealer. They charge excessive rates for an extremely shoddy service. Chrisssssssss..........
