Vox bad service

I work at a school. We were upgraded to Fibre by Openserve on 20 February 2022. Vox is our service provider. I tried to phone them on the 21nd of February and they answered the 10th time. I spoke to Wesley. He said he will e-mail me a quotation immediately. It is now almost a week later and no quotation. He is never available when we call.
