Hi Tam.
1. You can ask that. We can not name the clients of a particular mystery shopping company, but we can mention the type of shops they have.
By phone shop, do you mean a shop you do on the phone?
I have done phone call shops for spotcheckservices, servicemetrics, lanla, consumer connection, shoppers confidential, research services group, bare international. I come across them infrequently though.
I've done shops that were checking out a website for bestmark, and for shoppers confidential.
2. I haven't tried them. I do use the recorder on my cell phone.
3. Market Force sends me a cheque. And I think Mintel.
