Waiting for bloodpressure meds - will they be held liable if I get a stroke?

This pharmacy does not event deserve one star. I ordered my and my husbands chronic medicine on 1 September, by 11 September I have still not received anything. I phoned daily to get feedback and all they say is that the medication will be dispatched the next day. We both suffer from high blood pressure and I would like to know if either one of us now suffers a stroke if they will be held liable as they are not delivering our required medication to keep to manage the blood pressure. The lady I spoke to know will apparently arrange a special delivery.... I think the chance of that is zero. Not pathetic service - this is no service.
