Definitely give them a ring Lucy, or ask at your WFI, the adviser you see should be able to find out what is happening for you. A letter concerning your recon should tell you whether they have been able to change the decision in your favour or not. If they haven't been able to change it, it should also include info about what to do and what will happen next in the appeals process.
Only one type of ESA is paid to a claimant, depending on which they qualify for. If you're unsure about which one you qualify for, again ask about it, either when you ring them or see your adviser at your WFI.
