I got something like that too. When I responded I got "reference". Gave them a reference and then followed up a bit later to find they blocked my number. My reference was a VERY reputable local.
My suggestionis contact other providers, do reviews, be active in the forum. That is what they rely on.. referrals doesnt mean anything to them. Then theyll ask u your handle here in perb and ask u to message them thru here..
I am also almost impossible to embarrass or gaslight . thanks for the unsolicited opinion though. I am very aware of my silliness. I envy your unawareness. Likely makes life a bit easier.
