We're having a party in the summer and I decided to get some invites done rather than writing them all out myself. So I went to an invite printing website and designed my own. They have a red chilli design on the front (it's a BBQ) and the party details on the revserse. I checked the proofs online and it all looked fine and ordered them.
They've arrived today and they are OK apart from the fact that on the reverse in addition to our party details info (which is all printed correctly) they have printed in tiny writing up the side of the invite on the right edge "designed online at www.xxxxxxxxxxxxxx.co.uk".
This was not visible in the online proof nor can I find any reference to it being on the invites anywhere on the website (inc. the T's & C'c).
Should I complain and get them to re-do?
