Jebson is junk

On the 12 of November after work I bought a Jebson smart car audio tape.. Apparently there policy is have it fixed by a credited business... But even if it was installed at a sound audio place if there is something wrong with the tape I'd still loose out money right? Indeed!with years of experience and I was in the industry I fitted my new tape I bought myself.. Before I have fitted pioneer, jvc and Sony tapes with no problems lasting for YEARS!!! SO I fit the tape on the 14th it plays for 20 minutes and it didn't blow but the tape starts getting extremely hot, which it should not do and then the sound dissapears after 20 min.. When I entered the cash crusaders plumstead store it was tested for few seconds and that's it to make sure theres power and sound but bit long enough to test for faults . But then I contacted head office and they let plumstead know, the manager who could not help me because of head office **** policy, I took the tape in store and when they at cash crusaders plumstead tested it, the tape has power and not blown so I installed it correctly but no sound and the consultant acknowledged it was heating up... So to think 430 rand of my hard working money went down the drain and cash crusaders thought nothing of the fact that I lost money while they pocket my money and I'm left with a tape I can do nothing with, just stare at to collect dust and know i was ****** by a **** jebson quality .. They could of offered to have it repaired or send it away to check if it's faulty or reimburse me seeing it was not even yet 48hours since purchasing and that it played 20 min and after w Going to the store and they checked in store it heated up aswel and a bit of quiet sound, so that tape is faulty and was faulty .. There is no courtesy in cash crusaders and they have ripped me off and ****** my money and I lost 430rand and not even a hint of concern or compassion . Just words of sorry its our policy... Instead of jets send it away to make sure it wasn't faulty.. Its not like I had it for over 7 days but within 2 days I email head office... I want a refund so I can buy me a proper brand and fit it myself and show cash crusaders that you are a *******. A big ******* bunch of *******.. Very dissapointing in head office principal and no regard for its customers at all.
