Poor customer service

Poor service, bought a laptop battery on the 14th April 2023, received the battery on the 18th of April 2023, on the 19th April 2023 reported to the First Tech that the battery is faulty(not charging). They promised to collect the faulty battery within a week but only collected it on the 8th of May 2023. I have been emailing them continuously about feedback but no progress, as I am writing this on the 24th May I am without the parcel or way forward. Happy Maphanga was assisting with matter.
