Ceiling joists are only meant to hold ceilings up, and the occassional water tank when suitably supported
If this was an official `loft conversion` the local building control would be involved, not to mention drawings and structural calcs.
If this is not the case, I guess the instruction must have been from yourself. Whether or not the first guy gave you so called advise as to the practicality of the method used, I reckon you have little to no chance of recovering any monies from him.
Hope is the second crew have at least beefed up the joists/support scenario, and told you the area is only to be for light use of suitcase storage.

Well most ceiling joists are designed for light storage.. if your using the space as habitable area then expect ceilings to crack as 2929twin has posted..
