Shocking service

The most disgusting interaction I ever had was with this pharmacy. I ordered insulin from them on the 15th of March, they then delivered 1 vial of insulin instead of the 3 but promised free delivery of the remaining vials the following day. it never came. when the 1 vial was almost done on the 29th of march, I called them to request insulin in their business hours to no answer, sent whatsapps to no response, they were then closed so i had to arrange emergency insulin. they then whatsapped me on the 1st of April and confirmed the insulin would be there on the 2nd of April, on the 2nd of April, I got a call from them placing all the blame on me despite having their communication in writing, they said i was responsible to get a script (they confirmed script as per law by teleconsult with dr) and questioned why I would only follow up when i was on my last drops of insulin and how the blame isnt with them aswell as mentioning i should call them in business hours in reference to them not answering, I was speechless. . they have been paid for 3 vials and again i need to organize emergency insulin because they said insulin would be delivered today but now they arent giving me what I paid for. the responsible pharmacist is shocking and should take responsibility when making a mistake instead of spending the phone call placing blame instead of finding solutions. 10/10 would not recommend.
