Not refunded for a return

I submitted a return to Spree a while back where I combined 2 items in 1 box. Upon receipt of the package the courier said its no problem and checked that both of the items were in the box with the original \slip". To my surprise I was only refunded for one of the items!! The cheaper one of them obviously. When I realised this I logged-on to their website to see that the return was noted as \""expired\"". I immediately email their support function but to date have not received any correspondence (this was done on Monday). I also followed-up again on Wednesday but no reply yet again. This refers to return ***-1. I hope I get some luck by reporting it here.<br> Regards"""
