Bad customer service

I bought a laptop from teljoy ,first I waited nearly 3 weeks for it to be delivered then it gets delivered without a charger ,I logged a complaint and nearly a week later I still haven't received it or a call from anyone to apologize ,it was delivered on the 31 October so I am expected to pay for something I cannot use ,I tried to cancel my contract and get put on hold for more than 10 minutes only to be told I need to send a email,no one even bothered to ask why I want to cancel ,bad customer care ,I will never do business with them again nor will I recommend them to anyone
