City lodge OR thambo ripped me off

I arrived midnight from my flight from Amsterdam and I checked in at the hotel. City lodge OR Thambo. The reception guys took advantage of my desperate need of paying in euros as I did not have south african cash rands on hand. All the banks were closed by then. They charged me 140 euro for the night. Please don't ever use euros or any foreign currency at this hotel. They will rip you off and make you a fool. I had to pay 112 euro instead of 140 euro. The lady Carmen at the reception is very rude as well.
