ACCOUNT SETTLED IN FULL AND I'M STILL DEBITED!

So my account with BMW Finance was settled through another dealer on 16 March 2016. Yet, at the end of the March, I was still debited. Then, after calling around to get the proof of payment from the dealer, who I sold my car to, I then had to send it to [Email Removed] only to be told sent an automated reply informing me that I'll have to wait 24 - 48 hours for a response. Trying to speed things up, I call a customer service agent to try and get a direct email address, which isn't possible. When asked about the refund time, I'm told that I'll have to wait another 14 working days to receive it.<br> <br> Surely this is a joke and if it isn't it should be because it gets better. BMW Finance call centre doesn't take calls on the weekend. Ha ha ha.
