Delay in refund of deposit

Deposit was paid on a vehicle we wanted to Purchase on 03/02/2020. On 06/02/2020, an application was filled in for finance. Upon approval of the deal, the bank picked up that the vehicle's enjin was changed in the same year the vehicle was manufactured. Which obviously made us suspicious. We decided to rather cancel the deal, due to the uncer*****y of the enjin change.

On 10/02/2020, we asked with an E-Mail and telephonically as well to please pay back our refund. During the 8 days numerous E-Mails was send to their finance department as well as the Salesperson. Everytime there is a different excuse.
