****med by Cash crusaders

In October 2022 we bought the speaker from Cash crusaders with a 1yr warranty, in December 2022 we noticed it's struggling with charging until it didn't charge at all. We took it back and we were told to come back for it in 14days, if they can't fix they will give us another one, to our suprise when we went to fetch we were informed they can't fix it because the problem is not with the charging point but with the motherboard and that we will have to pay R800 to have it fixed, now my question with Cash crusaders do they sell **** to their customers with the promise of a warranty and then when the warranty has to apply its non existent or is this warranty offering just a **** into having people buying their stuff.
