I am a furniture salesman. The customer came to see the furniture once. How should I speak when calling a customer?

High-end brand furniture does not make phone calls, send messages or make plans, but only investigates who bought your brand near the customer's home; Mid-range furniture does not send messages. First, make a simple phone call to communicate whether it is necessary to go to his home to help make a plan according to the room type; Low-grade pallet fast-selling furniture only sends promotional activities or gift information. -Personal opinions don't call names.
