Bad service

We went to Kia Motors on the 7th to apply for a vehicle on the 10th of March the bank approved and we had to pay R55 000 which I paid on the 11th of March everything was going well until Theunis went on leave and he handed over our application to Phindile who my husband started communicating with her on the 11th when he sent the proof of payment for the R55 000 at 7am and Phindile never responded to acknowledge the proof of payment and we decided to drive to Kia Motors to find out if the proof of payment was received and when will the car be ready. Phindile told us that the car will be ready on Saturday Phindile doesn't even see the need to communicate with my husband, we are the once that needs to contact her, yesterday which was Friday my husband got am mail from her saying she was trying to call him which he acknowledged that he was unavailable because he was in hospital This morning @ 10:26 my husband called her and she said the car is ready she is waiting for the lady who has to assist us with signing the contract as she was not at work when my husband called at 10:26, my husband sent a a whatsapp @ 11:41 asking for an update and she responded by saying the system is offline and they can't pull the contract and we called around 12:45 to ask if we can get the car and sign on Tuesday and she said she is going to talk to her manager and get back to us, now it's 5:25 and we still haven't heard from her and calling her we advised her that we needed the car ASAP as it had to go work so now we have lost 3days worth of income because of someone's lack of communication
