Non existing support. Non existing interest in my problem.

I wish I could give 1-Grid minus stars. I have being having problems with some of my domains since the beginning of May 2023. I have logged about 5 tickets, through their website and by telephone. The people on the telephone have both promised to phone me back. None did. I have about 40 client domains on their Plesk platform and have no choice but to move my client domains to another ISP. This is how they treat a customer that has been with WebAfrica and 1-Grid for 20 years?
