Drivesure replacement Key

I filled in their online request for a replacement key for my car, giving the make, model and VIN and stated that I would be in Cape Town on 14/8/20. On the morning I received a whatsapp, "R2000" and later, "model", followed by "year". I phoned this number, and spoke to Lee, and made the appointment to meet at the BP service station at the airport. Leroy arrived with an incorrect key and suggested we continue with the programming, bud the blade will be cut and couriered to me. I suggested I hold back R500 until I receive the proper blade (part of the replacement key), and Leroy spoke to his boss, who asked to speak to me, and said he understood my concern and that the value of the key is more than R1500, but that his company reputation is worth more than R500, so would I accept his counter offer of holding back R200, with his promise that the key will be delivered by Tuesday, 18/8/20. I paid R1800 in cash for the programmed key and promised to pay the R200 balance, upon receipt of the blade part of the key. On Monday 17/8/20 I got a whatsapp "when are you coming to Cape Town again", I replied "not soon", followed by "physical address", which I had provided to Leroy, but sent it again. No further communication from Drivesure and no key received. I phoned Lee on Thursday 20/8/20 and expressed my dissatisfaction and asked to speak to the boss, who was not available and couldn't return my call. Lee offered to send me a copy of the weigh bill, which I was obviously not interested in, since I had bought a key and any issues with the courier was theirs. ABSOLUTELY NO FURTHER COMMUNICATION FROM DRIVESURE, AND NO KEY. Unprofessional, incompetent and unreliable.
