No response from Bounce King Staff

I bought a 4.2m Bounce King Trampoline. It got damaged in the storms from last week and I have been trying to source some spare parts. Everytime I call their call center the line either drops or the receptionist transfers me and then the line drops. I have been successful in getting through three times. Each of these times I spoke to Tanya who promised she would check stock and get back to me immediately. The last time she even promised to get back to me within an hour. She never did and i dont know what else to do but complain on a platform where I feel I will be heard.
