Bad customer service / poor administration

We have never had any issues booking a camping spot until now. We paid our deposit well ahead of time on the 10th of Aug. We did receive an email from the admin team stating that they received the deposit and everything is in order for our trip. Three weeks later we received further email correspondence from the same person who confirmed our booking and deposit paid stating that they will now cancel our trip as the deposit has not been paid. After some phone calls and laying down the facts they confirmed via email that our booking is still active on the system and they apologised for the misunderstanding. We settled the rest of our fees on 15 Dec and provided POP again. I asked them to provide confirmation in writing that our booking is still active due to what happened with the deposit. To this day I have had zero correspondence from the admin team. We have phoned twice already on the 19th only to receive empty promises of providing confirmation in writing that our booking is still active. The lack of communication is extremely unprofessional and I will most definitely be thinking twice before I ever book with them again. It is such a shame that this recent negative experience has spoiled our upcoming trip as well as the memories of previous trips. We have had such amazing times at Mabalingwe's camping site, but will most definitely be reconsidering any future trips. The total disregard towards customer service is shocking.
