Valcandy, I don't want to sadden you but I get the distinct impression that cool new mobile do not give cashback. They seem to have formulated their entire ethos in such a way that tricking customers out of their £360 cashback is their holy grail. The law for them is something to be negotiated like a rollerblader avoids obstacles.
I tried everything in my power to try to get my money from them to no avail.
http://coolnewmobile.vox.com/ I wrote this in the vain hope I could discourage others from wasting £360. I have never known anyone to get cashback from these unscrupulous firms. Is it possible to get cashback?
Anyone interested in pursuing this firm through the courts would have my full backing.
