I purchased a sony 90mm 2.8 gos lens before christmas with a £100 cashback deal. I am having a problem claiming the money back. Sony have confirmed that my receipt and photo are with the validation team but despite me chasing them up 3 times now i still havent had no joy.  I am now wondering if this is a scam as absolutely not what I would expect from Sony. Is anyone else having same problem and who do I complain to.
