AllegroMedical.com / Stole my money

I placed an order with them, and subsequently returned a portion of that order to the amount of approximately $90. McKesson was the distributor for that return. I was issued an RMA number and return the items directly to McKesson, which they received because I used USPS tracking. McKesson issued a credit to Allegro Medical for the return, but Allegro kept giving me the runaround why they couldn't issue ME the credit. There was always a new excuse. It's been almost three months now, and I know I will never see that $90 again. I think I will write a personal letter to McKesson. I think I will include some of these complaints that I am reading here. Please, all you good people, AVOID ALLEGRO MEDICAL. THEY ROBBED ME. I SEE NO REASON THAT THEY WOULD DO ANY DIFFERENT WITH YOU.
