thanks everybody - your info is brilliant sorry I 'hijacked' a thread - bit of a 'newb' as my son says! will get better! thanks again

hello again to all at the group. bit mew at this so please bear with me! my friend has received a vet bill for £39.00 which vet states she owes from work done to her dog seven years ago. my friend is adamant she paid at each visit for any treatment. this is first contact in seven years even though she has not moved house for about ten years. she has no proof she paid it and tried ignoring letter but vet now threatening her with solicitor. she did ring vet then to say dhe does not owe this money but they insist she does. Is there a time limit on sending out bills - what can my friend do next thanks Greenway
