Delay in sending the Paid Up letter

<p>I had an account with Woolworths and I struggled to pay the account.Then I was handed over to MBD Attorneys. Last week, I settled the account and sent the proof of payment to MBD Attorneys as instructed. They then assured me that they will send the paid-up letter not later than 7 October 2016 as I urgently need it for my credit profile to be updated so that my Homeloan application can be approved. Still today am awaiting for the letter and they hadnt sent it yet. Ive tried to call and e-mail them and there is no response. I am so frustrated because the Estate Agent who is assisting me is waiting for the letter so that they can proceed with the purchasing of the house. While I was owing, they were busy harassing me telephonically,now they dont want to give me the paid up letter.</p>
