Horrible service from the admin staff at Helen Zille Wing of the Palm Garden Retreat Private Nursing Home

Dear Hello Peter please can you help me. My mother was admitted into the Helen Zille Wing of the Palm Garden Retreat Private Nursing Home for post stroke neuro-physiotherapy on Tuesday the 11th of February 2020. She passed away on Friday the 14th of February 2020 and her the total amount of her stay at the retreat tal**** a total of ZAR8,850. I had pre paid an amount of ZAR43,125 and on the day of my mom's passing, I received an email from the case manager (Ms. Lauren Davies) confirming that I would receive my refund (R34,275) on Friday the 28th of February 2020. The retirement facility banks with Nedbank and so do I, so interbank transfers reflect on the same day. When the refund amount of R34,275 was still not reflecting in my bank account on Tuesday the 3rd of March 2020, I called Palm Garden Retreat and I spoke with a lady by the name Charmaine who works at the admin/finance department of the retreat and she assured me that the funds would be paid into my Nedbank account before Friday. On Thursday I called Charmaine again and I was referred to their finance guy whose name is Lado who assured me that my refund had already been credited to my Nedbank account and would be reflecting by first thing the morning of Friday the 06th of March 2020 which was today. I called Lado and Charmaine a total of 20 times today and I was repeatedly assured that the director of The Retreat who needed to sign off the payment was in a meetings since 06:00am this morning up until just before 4pm and could not be disturbed, which was clearly a lie. Following my mom's passing, I enrolled my daughter at an international school in Cape Town. I explained to the staff at Palm Garden Retreat as well as forwarded them an email from the school stating that my daughter would not be enrolled or allowed to start classes at the school on Monday the 09th of March 2020 until her registration fee and 1st term fee of ZAR25,000 had been paid upfront. Please can you assist me to just get my money back.
