Dual citizen living in Canada no Canadian income trying to get the same person I had last year for premier full service

I have tried numerous times to get the same tax preparer in full service premier Canada TurboTax to no avail I have given them the name of the person they reassure me he’s working this year, but I don’t get any communication. It is important to me to stick

with the same person as I am a dual citizen, filing taxes in both countries with TurboTax
