I want to make a claim because in FARMACITY I charge a higher and higher price than the one that appears in the box of the MEDISOL brand medicine, 42% more than the price that the box informs, I contacted the telephone 4105-4100 and no one responds from the LABORATORY PABLO CASSARA ,, does not answer on the FARMACITY phones, they abuse the consumer and charge the prices they want and no one is responsible
