Hi all. I hope that the following helps some unhappy bunnies who have been getting nowhere 
!
Until recently (I think the start of February) the cashback programme was run on behalf of Lenovo by Opia UK Limited in Gateshead, although the cashback promotion is actually looked after by their Harrogate Branch.
Their email address for queries was help@lenovocashback.com, and their phone number was quoted as 0845 0515 121.
As of 14/02, this number works still but for all those people who don't like dialling 0845 numbers as they are chargeable within their call packages (mobile or landline) I have also managed to source the following geographical number which will take you through to their head office (ask for Harrogate customer services) - 0191 440 7157.
The cashback promotion states that payment will be made within 30-56 days, but after talking to some of the staff there payments are running out towards the end rather than the start of that timeframe. I can recommend speaking to either Vicky or Mia, as they were both very helpful to me. I haven't received my monies as yet, but I remain hopeful that now I know who to speak to (and where to track them down!) after a bit of badgering I will receive my payment eventually. I'll report back with any further progress!
The cashback promotion is now (and has been for a little while) run by a german firm called techprotect. The new email address ( for any recent claims) for them is lenovo-promotions@techprotect.de
If you need to contact the company (because they are ignoring your emails) their contact details follow:
TechProtect GmbH
Schickardstrasse 30
71034 Böblingen
Germany
Phone +49 (0)7031 7632 0
Fax +49 (0)7031 7632 100.
Don't forget when dialling from the UK that +49 actually dials out from landlines as 0049, then take out the 0 dialling code number shown above before keying the rest in i.e. 0049 7031 7632 0.
They claim to be able to speak English on their website so they'll have no excuses 
Good luck!
Chris.
