Without the requested information, I can only provide you with some general information on this topic. Hopefully, it will still be useful to you. First of all, I am sorry to hear about the issues brought up by this. It must be a frustrating situation to be going through.
Initially, you should try and raise a case with ebay over this as they may potentially be able to resolve this on your behalf and get you your money back.
If that is not possible, you still have consumer rights against the seller directly. When a private consumer makes a purchase from a business seller, they have certain 'statutory' rights under the Consumer Rights Act 2015. If you wanted to refer to the legislation directly, please follow this link:
The Consumer Rights Act 2015 specifically states that there is an expectation that goods must be:
- of satisfactory quality – they must not be faulty or damaged
- as described – they must match any description given at the time of purchase
- fit for purpose – they should be fit for the purpose they are supplied for
If they do not meet the above requirements, the consumer will have certain legal remedies against the seller. Any rights against the manufacturer will only be under a manufacturer’s warranty or guarantee that came with the goods, which is entirely separate. It is, however, important to note that there is no protection against fair wear and tear, misuse or accidental damage.
