Terrible conference Venue

Our company had our conference at the Season Golf, Leisure and Spa in March. The service was horrific with poor communication, delayed catering and just a heap of problems from start to finish. Mostly they are sitting with money owed to us as we did not use our full bar tab. They said they would take 21 days to process the refund and we are long past that. The communication and updates are dismal. I have requested to talk to higher management to address the poor service we got but no response. We are out of options and at our wits end! Hello Season Management please can we have our money, thank you?!
