Takelot BAD Service

I order some flea collars from Takealot, which promised to work for atleast 8 month and came with a 6 months warranty. After less than 5 weeks my cats were riddled with fleas and fleas even sitting underneath the collars. I called and logged a return and dropped the collars off a Milnerton on the 3rd of November 2020. In less than an hour I got an email from them acknowledging the receipt of the faulty products and stating that they will test it to see if it is defective. Today the 6th I checked to see that the return says concluded. Heard nothing from them and no refund either. Called and a lady told me that they person who took the items in inspected them and declined them which is Bull****. Why the email then. The she says that she doesn't know why it's declined and will find out and let me know. I called at 5.05pm today, just to get the answering service that their staff needs their sleep. What a flippen joke. An hour before you close time your lines are shut down. TERRIBLE SERVICE. I don't even know if this will get an response as I see Takealot doesn't care about their clients, so they don't answer back.
