thats nowt mate dont get stressed , i had a custy last night who had left a message on my answering machine , she called to say that i had mistakenly overcharged her husband when out collecting by £1.00 and was really very very worried and concerned about this , she also said she cant understand why the original price of £6.00 had increased to £7.00 ( might have something to do with the extension she had built ) , she insisted that i must call her asap to discuss this matter as really was concerned and was considering canceling .
Absolute genuine mistake on my part had a lot on my plate lately due big workload and various other problems , husband probably never told her that when he paid me i was going to give him far to much change until he corrected me , which would indicate i was not thinking straight at the time ,
