Problem with buyer

I have a problem with a buyer , he bought my Upright Freezer on the 21st August. I sent him the invoice with instructions to pay cash upon  pickup , gave him the address.  and times he can pick it up .

I waited for his call and 3 days past. Finally emails and says he forgot he bidded on it.  Him thinking i was despareate for the money he wanted to direct debit the money. I first refused then later texted my bank details.

Now it's the second weekend, it's 12 noon , still no reply to countless emails and sms . No reply. Guy must be dam busy?

 

 

What to do now?

 

Can i can tell him  it's off , send the money back  and cancel the transaction. ?

 

or                     Wait ..............forever for him to contact me

 

If i had a van . I'd dump it at his place.
