Valentine disaster

This rating should actually be no stars. And please people do advise if I am over-reacting. So here is my story: My partner bought a wikideal voucher for McPhersons last month and on the 31Jan 2018 we called to make a voucher booking for the upcoming Friday 2 Feb 2018. McPhersons then called us that very Friday to cancel our booking due to the fact that they have a private function (now bare in mind, the terms and conditions on the voucher states that we customers shud cancel atleast 24hours in advance but they 'McPhersons' can call you as the customer on the day to cancel) Anyway we decided to use one of our other vouchers for a Town restaurant on that day. I then checked out their terms and conditions and all it states is voucher avail Mon-Fri and booking must be made etc. I then told my partner the 7th Feb to call McPhersons and ask them if we are able to make a booking for Valentines day as the terms do NOT state (not available on public holiday or special event nights etc like other deals stipulates (eg. Casa bella) He then called 7 Feb 2018 a spoke with a male advising we have a wikideal and would like to book for the 14 Feb 2018 @ 18:30pm. We were then content and happy to have secured a Valentine dinner booking well in advance. So yesterday round noon my partner calls me to say i just double checked to confirm our wikideal booking and all is in order. He even said the gentleman made a joke with him, asking 'so how many girlfriends will u be bringing along'. Anyway so we drive after work on a week night in traffic, all the way from Plumstead to Tableview and still call them to say we will be slightly late due to traffic. Upon being seated and asked if our orders cud be taken we discovered by the waiter that we are not doing voucher bookings tonight only a set menu which costs R200pp. Obviously I ask to speak to the manager Luke to advise him that we have called twice just to confirm this booking as we came all the way from Plumstead. His exact words were people make mistakes, thats life, but you cant blame me for someone else's mistake. We dont have any burgers in our kitchen only this 3 course set menu today. With that being said I obviously did not feel like staying there and I personally feel that They should be liable for our petrol of 26km travel too and 26km travel from and also the money we spent on supper in the Blouberg area which was absolutely unesseceary. My partner felt so bad and I was also very disappointed in the way the issue was handled. Becoz its not like we stay around the corner they cud have made a concession to give us some type of burger as we followed all the rules as suggested on the terms of the wiki deals.
