Absolutely terrible. Waited 7 weeks for a phone replacement that should have been done next day. Everybody in customer service told me a different service. Replacement phone was sent to a random address in Coventry (I'm in Sheffield) and they refused to send me a proper replacement until the person they had randomly sent it to chose to return it. In the end they gave me a replacement in store which they swore on day 1 they could not do... At upgrade time my wife and I both upgraded at the same time on the same telephone call. They sent us both a phone, and then despite having taken our money told my wife she had failed a credit check and could not have the phone. We checked with Experian and no credit check had been done. We got a whole bunch of lies, slander, and libel from a whole bunch of operators and in the end my wife's upgrade put her £100 out of pocket on the deal she should have had, was promised, and was sold. Customer services have two issues outstanding for at least 3 months now and are not returning my calls - yet they have asked me to write an honest review. So here it is! Hope this helps. I'm not afraid to publish this as it's fully true and I stand by all the statements made. I can't think of a single reason to bother to use Phones4u in the future. Avoid.
