Staff problem and service

Very disappointed with service, Trish is the sales person who helped over whats app, all paperwork was submitted to him for a purchase of a Ford mustang priced at R589 000. All has been approved so I told him I'm bringing a trade in as well, because of a busy life I was going to do the deal with 1 go once tested. He should of mentioned what needed to be brought to conclude with the deal, unfortunately nothing was said. I asked him to get the car ready because I had to travel from Mt Edgecombe to PmB, got there car is still in lot not washed. Waited for that to get done in order to inspect and take for test drive. I did a short run and was happy to conclude the deal. Suhale helped with rounding of paperwork to Westbank, my ID was required which unfortunately I did not have on hand, 3weeks later Trish asks when can I bring ID through. My temporary disk is expired which Suhale says if I get stopped to just mention I'm on my way to pick it. My biggest problem is this, while I was in Cape Town I got a message from tracker vehicle battery low, I messaged Trish to have this seen to 14/04/2024 with no plans forward, I contacted Suhale the manager and explained these issues, he guided me how to open the door and access the bonnet. I arrived back 22/04/2024 and mentioned to suhale the battery is stone dead. The advice I was given is to jump start the vehicle, bring it to pmb so that they can take it to a battery specialist for a report. I am not a mechanic to be doing these things and running around especially to purchase a vehicle at that price, no spare key, manual, service book, wiper blade needs replacement. Not happy with the service, owner should look into these small flaws with staff to make sure the customer is getting a proper service or else it could just ruin a good business.
