Slow lounges - ambiguous terms

I have a platinum cheque card with FNB. According to their site, I quality for 2 visits (including guests) during off-peak times. In May, I visited the lounges twice with a guest (thus 4 entries). FNB charged me R500 for the second entry, as according to them, I only have two entries in total. The wording on their site is ambiguous as I interpreted this as two visits (with a guest). They also attempt to explain entries, but this does not refer to a specific class:<br> <br> \For your benefit you may use your 4 visits during off-peak times in the following ways:"<br> \""4 separate visits for the cardholder only or 2 visits with one guest each time or 1 visit with three guests or 1 visit with two guests plus one visit for the cardholder only\""<br> I did log this via premier banking and I got a call from someone trying to explain this to me like an idiot. I understand what you want your policy to be"
