Unhappy client

I requested a quote from Windovert ZIB INDUSTRIES PTY LTD, Margate, after a windstorm damaged my Carport Shade net. Jaco and I both inspected the Shade net and there was ONLY the loose front seam and a small cut on top WHERE 2 construction parts joined. Jaco said no problem they can remove the shadenet and ONLY have it stitched and patch the top cut piece. Then reinstall it again. R2875.00 He said a week at most. He send it in Monday and depending on receiving it, if a Friday fix it the Monday if receiving it Monday then Tuesday. They never updated me, I had to make a call 3 times. They did not make a note, it was NOT IMPORTANT, maybe that is why they ALSO not updated me. When the Net was eventually fitted after 2 weeks, there was a slit on the other side that was fixed by hand. Handstitced. It looks horrible and is now easy for further damage. After quoting for the insurance, and I've send the quote and received payment, Jaco called and said if I pay another R1000 he can order a brand new Net. I explained I am a pensioner and don't have that kind of money. He said okay R800. I declined. He is in the business at the COAST, I retired recently, WHY DID HE NOT ADVISE ME TO REPLACE THE NET WITH A NEW NET from the start! Now attack to defend himself saying he told me the Net is already 4 years, I should have ordered a new net. He don't want to have a unhappy customer, so I can decide if and how much of the balance I want to pay. Penny wise pound foolish, as that damaged part will sooner than later cost me another fortune. This time I will order direct from the manufacturer and cut out the middleman. Pensioners on the South Coast learn from this and don't fall in the same trap.
