Choosing money and breaking already agreed on terms over loyal customer

We tried to book the venue and spoke to 3 different people every time we went there. Promises were made and it was agreed on afterwhich on our last visit all agreed on was just a sorry this is how we can help you. Suddenly we had to pay R15 000 after they agreed that we must only spend an X amount on the day. Worst bussiness etique ever. We wrote a mail a week ago to them to which no one has come back to us yet. When bussiness were bad they could make promises but as soon as curfew was lifted they did not need us the valued customer during lockdown anymore and took the high road turning their backs on us choosing money above loyalty. If anyone was thinking of using The terrace. Think twice as there is many other businesses in Durbanville who would welcome you, or get all on paper.
