better business bureau useless company southfield Michigan

i made a   complaint to the BBB about quicken loans. its baffling that that company has an A+ rating  from the BBB. the BBB notified me of the receipt of my complaint. one week later they sent an email stating that quicken loans responded to the complaint and  told me there was an attachment  enclosed. there was NO attachment in the email, none!  i wrote back to the BBB stating there was no attachment to respond to.   

today i got an  email saying my  complaint is closed  because i did  not respond to the  company's  response. i most  certainly did. i responded that the company response attachment was missing from the email. so exactly how does the BBB help the consumer. i think they are another fraud.
