Disappointing Support Services via Email

Even though I think Register Domain SA is doing their best in providing some sort of Support via email, I have found their Support services to be rather disappointing, due to the absence of an actual call centre. Perhaps it is due to the fact that their staff are working remotely because of COVID 19, but I am finding that their service via back-and-forth emails ineffective in resolving my queries. For some queries, the needs of their customers would best be served by having an actual call-centre, to deal with any customer difficulties live, as opposed to the back-and-forth emailing. I'm rather frustrated right now...
