Good evening.
I am very sorry this is so late but I wanted you to know that I have recently had my assessment/interview with Post Office and passed with flying colours.
If it wasn’t for your help and guidance, I don’t think this would have come about.
I just wanted to thank you for the time you spent on my application and the advice you gave me every time I called for help.
You were so very supportive.
With kind regards
Lynne
