incorrect phone from blue lable

Hi my name is paul britz i have taken a phone out and was given the wrong phone last year I have contacted blue label customer care they told me they know about the phone and I will receive my new device in 3 working days it gone 7 months now and still haven't received it so in December I stopped the payment and they have still not responded because they don't care for there customers I want to report this matter as I will not pay this phone anymore
