Parking fine, is it legal?

[hot wheels]

i'm bloody angry
parked up last night(8.30) in manchester opposite the comedy store in a side street there were no official parking notices or yellow lines just one of those private clamping signs
I've come back to the car and theres a parking ticket on it but from a private company
The fine is £70.00 rising to £110 in seven days and there is just a premium rate number to complain about it.
Is this legal and enforcable? it seems like a scam to me as i'm sure in every normal respect i was legally parked

thanks for that it looks like its the same firm thats mentioned in the articles "Excel parking" from sheffield, i'll certainly be looking into this and if theres any chance of a fight i'll take it. I hate buracratic bullies and i wasnt aware this was a private rd and at seventy pounds its almost double the normal fine
the premium rate number to complain is a scam as well

What is the name of the company?

just an update
after lengthy investigation i couldnt officially establish ownership of the road in question but confirmed that there are no officialy sanctioned independant parking inspectors in Manchester councils environs
On their own parking departments advice i chose to ignore the ticket and if contacted deny recieving it and ask for evidence of the offence (noting that they have no powers to convict )
to date i've heard nothing at all.............
