Appalling service

I bought a laptop on 24th November 2017. To date I have phoned, emailed and visited the store and still do not have an expected delivery date. No one answers the customer care phone (have phoned 6 times) or the email. I have phoned the store 5 times and been redirected and fobbed off till my head spins. I have visited the store 3 times and nobody can help me and I keep getting told to try again and I am not the only customer complaining. No surprise there then. I am now going to demand a refund and without an apology and/or explanation I will never shop there again and shall loudly and repeatedly tell to all that will listen to spend their hard earned money at a shop that respects their customers Disgusted.
