When I wrote my original review, I forwarded it to the branch manager of Holiday Inn North American and his office acted promptly on it.
They have given me their sincere apologies, and offered me 8k hotel points, which translates into 8 Southwest Rapid Rewards Credits, which is about have of a frequent flier ticket. This is in addition to the half price my part was charged for our overall stay.
They explained that the Charlotte Holiday Inn is a franchise and independently owned and operated, however they are working with relevant mangers to resolve the issue I experienced.
Thus I am happy with their response and compensation, even though it was a harrowing experience, I think we can all look back and say we are better people and hotels for having endured it.
However, please read my original review for helpful advice when checking into hotels....i.e. use a credit card rather than a debit card in order to protect your funds.
