account closing

<p>i had an account with woolworth. they called me in october and gave me a settlement discount. in november i called back to inquere if it was still valid said it was. end of November I settled the amount. since then daily I have received calls , consultants telling me my account is still outstanding, when i offer to forward the proof of payment they dont want it they insist it will update and they will send me the letter proving i have settled. i am aware that the letter can take 30 days. however i am unclear of the daily calls I receive 3 times a day. this is harrasment, i work in an invironment were i am not allowed to take personal calls they has put a strain on my working relation with my senir. its frustrating . all I want is a letter to prove i have settled the account and the phone calls to stop </p>
