Dear Sir/Madam
I am moving from my current address to Flat 1 Helen Mews, Helen Lane Weymouth, DT4  8AX. 
Can you please cancel my account from 31/03/16 and send any correspondence to the Weymouth address. Do not call the number above as its not correct. reason for not giving you correct number is that I work in a surgery during your normal working hours and will be unable to take your call. please contact me by either post or e-mail.

Kind Regards

Sharon
