A Jacket instead of shoes and two months with no resolution

Ordered a pair of shoes online, received a leather jacket. Phoned TFG onlineshop immediately and was told they'll log for correction. One week later phoned the courier and they were unaware. Emailed TFG 24 June with a photo of the two waybills and order number and received an auto response. Emailed again 5 August and 8 August received "we have forwarded your query." 17 August, after I had sent them of all the information I received for the package, I am asked by email what I did not receive. I still have a jacket I don't want, and no shoes which are no longer in stock. The initial error may have been the courier sticking on the wrong waybill but TFG have failed miserably in their response to what should have been a simple fix.
