      a timeline with  -
      date you parked car
      date you went away
      date permit expired
      dates with PCN numbers of each PCN
      date of removal to pound
and   date of your going to pound.

Then

They said if I release the car, that will cover all liabilities.

Who said? Verbally? a letter? 'phone call? e-mail?

So I released it; I gave them the keys and the V5C. I signed a contract; I have proof.

Who is 'them'?   What is the proof? Please post up here a copy of the contract. Were you given anything else at the pound?

Now I am receiving letters from Tower Hamlets Council demanding payment for 8 different PCNs from the same contravention!

Please post up one of these 'letters', assuming that apart from dates and PCN nos. they are identical..

When posting docs here, redact only name & address - leave all else in.

Sorry about all the questions, but without the details it is nigh impossible for the experts here to give meaningful advice.
