Emails Lost for three days - cannot retrieve!

From the 6 October 2025 till today, I have not been receiving my emails. I have called 1 grid, spoke to Viwe Mdan***i for the past three days, TOTAL waste of time. Today he spent the entire day saying he was retrieving my emails with no success. Eventually I asked to speak to his team leader Peter Hosman, and he kept me holding for 30 minutes because he was on the call. He eventually showed up to tell me that "unfortunately they cannot retrieve my emails for the last three days. I hate 1 Grid's service! it is pathetic! please anyone give me suggestion of a good company that I can go to.
