Car seat discount not worth the trouble

I have been trying to claim the car seat discount since middle January. 2 of the Wicodes I received did not work…. I needed to get a car seat urgently and they have not refunded my discount. I have sent numerous emails and the response I get every time is that the query will be handled within 48 hours. I am really disappointed in this service! I have always been a loyal customer, with all the Discovery products. I can’t believe something so simple takes so long to resolve.
