Problems regarding servise plan

Since 3rd of January 2022 until 7th of January, I tried to get hold of the service department. I left 5 messages for service department to come back to me. For the service manager Madelein I left 3 messages, but no responce. Because I stay 1 and a half hours away from Kumberley, I wanted to make sure about the booking I made on the 3rd of January 2022 for 11th January 2022, at reception. I also wanted to know if my extended service plan was still valid. Nobody ever came back to me. I poned again on 7th January 2022 and spoke to Madelein to confirm the service plan, she eventally confirmed the booking. We left the car on the 11th of January. Magda said that she that the plan was active, but that she will let me know of any problems. Although she tried to contact me there was a problem with my phone but I did not know about it. At 16:15 I went to fetch my car, but no service was done as Magda said there was a problem with service plan. She said if we are prepare to pay they will do the major service. Then we could sort it out with LiquidCapital afterwards. In 30 minutes the major service was done. I feel if they did contact LiquidCapital between 3rd and 11th January 2022 all this problems would have been avoided. I feel if they came back to me regarding the service plan before I took the car in, I could have sort it out before I took it for the servise.
