Shocking Aftersales Service

I purchased a Gentech GP4000 generator from a Gentech registered reseller in June 23 to help cope with load sheeding. By August 23 the unit would not start due to a faulty battery, I sent it into the local agent in CPT who "fixed" it. Since then, the unit has given me endless problems, it is now back again for the fourth time as it will simply not start at all. I have only had this unit running for no more than 15 hours, it has spent most of the 8 months being "Repaired" The service I have received thus far has been shocking too say the least, no communication what so ever. When I told them after sending it in for the fourth time to be fixed that I now want the unit replaced as it is still under warranty, I was promptly told, "sorry our policy is that we do not replace units, only repair" completly against the CPA. Do yourself a favor, don't ever purchase a Gentech prodcut.
