I resat A-level chemistry and got in everywhere i applied to. I would give them a call and have a look on their website. i know some places increase their offer if you're resitting a subject - however you are looking to resit more than one so it is definitely something to talk with the admission tutor about.
If they're adamant you can't go there have a look at other universities, if you're looking at strathclyde then i wouldn't dismiss RGU or Sunderland either. Some of these places may offer a foundation year or the chance to do pharmaceutical sciences for a year with a view to cross over to pharmacy if you do well in the first year. Just be warned that you are still not guaranteed a place in pharmacy if you go through either of these routes, i think the flow-through rate is usually around 5-10% depending on the grades and the uni.
