Pre auth. Money.

Upon check in I was asked to pay a previous authorisation amount of R3000.00. I was advised that on the day I check out, the full amount of R3195 will be deducted from my account and the previous authorisation amount of R3000.00 will be reversed back into my account. That was last week Thursday morning at 5am. Today is Tuesday 5pm. I have spoken to countless people and have received an email saying that it's Nedbanks fault, but no SOLUTION has been given to me. I want my money back in my account by Friday morning. This is absolutely pathetic service from such a reputable brand. I am very disappointed and have advised my company to not book any of our travelling staff at this hotel from this point onward. We have been booking people there for almost a decade.
