AFHCO IS IGNORING MY REFUND REQUESTS

I have called AFHCO hundreds of times demanding my deposit refund but all I get are promises to call me back.

I am being told that my notice to vacate, which I gave to the Building Manager of Stuttaford House, Sam, at the beginning of August, was not received at head office. I moved out end of August. I do not know how many times have I called Customer Service demanding they follow up on this issue, but nobody is taking it upon themselves to rectify this mistake. I am so furious, and whatever credibility I had for this company has gone out the window. It wasn't enough that we spent many winter days showering with cold water at Stuttaford, now they are refusing to refund my deposit.
