No response from Riverside Hotel

I called the hotel on afternoon/evening of 25 May to make a booking with banqueting for a function in July. I had to hold on for ages, only going back to switchboard once and being told to hold on again. I had to call back again and asked not to be put on hold again and if JOanne in banqueting was in. I never got to speak to her and have sent her an email. Still no response from her today. Called this morning 26 May, spoke to Candy, was put on hold, didn't reach banqueting. Called again, was put on hold by Amanda, still not got through to banqueting or even know if there is anyone in banqueting that can assist. I called a third time to speak to general manager Gerard Flaus, Rang for about a minute, someone picked up but this person (not sure if it was him) was on another call and I ended up listening to someone talking in what I think was German, next I am on hold again.....well needless to say, I put down and will NOT use this hotel for a function booking.
