Neotel's slowing my bond approval, uncontactable!

My bank requires a letter from Neotel stating that I do not have any unpaid accounts with them. This is in order for them to approve my bond application. <br> <br> I left Neotel in January 2014, due to poor service, and my account was settled with them soon after that. I have an email from the time showing this, but my bank requires a letter in pdf form confirming this.<br> <br> I am now being exposed to the poor level of service in this company once again, even though my request is extremely simple.<br> <br> I cannot reach anyone at Neotel, not through any email address on their contacts page, or through any call center routes.<br> <br> Wow! What a company!<br> <br> Please help!<br> <br> <br> <br> <br> <br>
