Useless Key Chev

In August last year my Opel Meriva had a gearbox seizure and I took it to be repaired. I was told that I needed a Gearbox Code to complete the jobI contacted Brokensha's in Escourt to request such a code. They in turn contacted Key Chev in Maritzburg. Key Pmb sent Brokensha's a RADIO code and a KEY code but no Gearbox Code. Afer nothing happening I asked my repairer to contact Key Ptn this year, who in turn wanted R 1 500 for it, but to date nothing has happened as well. After contacting Brokensha's again, they in turn contacted Key Pmb who now told them that the RADIO & KEY codes are all thats available. All this going on is also supposed to have taken between Opel factory in RSA and the Opel factory in Germany. I do not thing that KEY Chev has any idea of what they are doing, if charge for a few numbers that should be supp**** with the vehicle do they also supply vehicles without spare wheels. This saga has been going on for nearly 7 months now.
