Fine choice/ home choice faulty electronics

Unhappy client I bought my laptop at fine choice with my home choice account. I started having a problem 4/ 5 months. I called them and I was advised to return it.. They kept it for 3 months without any updates instead dealing me to pay for something that was not even in my possession. They returned it, guess what, there's no laptop charger. I can't even switch it on to check if the problem was sorted. I called them again about the charger, it's been 3 weeks without the charger, mind you I can't use the laptop because the battery is not charged. Yet still they are calling me demanding that I pay, l still pay but no charger. Meaning I'm paying for something I can't even use. What a poor service and faulty electronics. My husband bought the tablet, experienced problems fine choice never sorted it out.
