Cash Crusaders - WORST COMPANY TO PURCHASE ANYTHING FROM

Cash Crusaders has been one of the WORST company to deal with. Nobody that works there is interested in helping me to resolve my issue! My issue is that I bought a Doogee S51 phone in March , all of a sudden the power button stopped working. I took the phone back and they sent it away for assessment. They stated that the phone needed to be quoted to be fixed however they cannot quote due to not having parts for the phone. I cannot understand how they are wanting to quote me yet my phone is under warranty . They are refusing to fix it under warranty due to a small dent on the left hand side of the phone. The power button is on the right hand side . How can a dent on the left hand side affect my power button. Phones I have had in the past have been dropped many of times and that never affected my power button! To make the situation whose , there are no parts to fix the phone. I really just want answers , but no one at cash crusaders can give me any answers. I don’t know what the employees are doing during the day that they cannot give me answers on my phone. I have sent emails and tried calling the branch many times however NO ONE has responded. I just want a refund because the phone clearly cannot be repaired. The phone has been sitting with them for over a month and I unable to use my phone which I urgently need for work purposes hence the reason for purchasing my phone. I am very angry about the fact that I spent so much money and now I am unable to use the phone and no one is giving me answers.
