Bad customer service

I have been contacting Pansula Workwear for over a month requesting for a quote. I received a quote once on the 21/09/2022 but it was incorrect. I asked for amendments to my quote and to date have not received a response. I have emailed and sent messages multiple times but have not received good service. It is as though because I am a small business, they do not care about my order and just don't care about the business. Really bad customer service.
