I would exchange it, buying a snake that never shed or eat is a big mistake, because you do not know whether the animal will eat or not, some just fail to thrive even in the hands of the most experience keepers.
I do think you have jump the gun a little in assisting already especially 3 times.
At 73 grams upon purchase and knowing it just hatched I would not have done anything just yet, when I have trouble hatchling I usually offer 6 to 8 times before resorting to force or assist depending on the weight and based on his weight you jumped the gun and assisted too many times already and too soon considering the hatchling is about a month old.
Now if you want to keep him there is a 101 for hatchlings in the advance husbandry section.
