Coolant level may be low, heater core could be clogged, thermostat is bad or the waterpump.
I would have whoever flushed the system, flush it again at their expense and have them check the waterpump weep hole for leakage and flush the heater core seperately to make sure it is not clogged and change the thermostat.

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
