Hi, I purchased a moto e and bought an unlock code on eBay. I tried to enter the code but I was unable to because my phones sim card slot was faulty. I've had to return the faulty phone so I no longer need the code. I know this isn't the sellers fault and the money I paid for it was pittance but I just wanted to know if they were still allowed to refuse a refund. Any help would be appreciated? Thanks.
