Bad service

I sent a script to Pharmacy direct on the 30th of March. I got an acknowledgement sms and email on the 1st of April. I tried to follow up on the 4th and 5th of April and I'm being told by different people that the meds were dispatched on the 25th of March which is obviously impossible. These are chronic meds for asthma why would you make an asthma patient wait for weeks for medication? No one can give me any feedback but they confirmed on the 1st of April that they have received my script
