Opel Corsa Lite PROBLEMATIC Clutch

I am so frustrated I have no words... BUT HERE IS JUST A FEW... I bought an Opel Corsa Lite 2007 model with 20 000km on in 2008. A year later in July 2009 the clutch cable snapped and I replaced it at GM (2 years from when the car was manufactured!). In Dec 2010 the clutch cable snapped again and they told me the clutch pedal also needs to be replaced and I had that done too at GM. In March 2013 it snapped again... I bought the GM part from Reeds in Cape Town and had my own mechanic replace it. Then in August 2013 the cable snapped again... and I had another GM cable fitted and replaced by another mechanic. In July 2015 it snapped again and I took it to Reeds N1 City and had it replaced. They told me that the clutch pedal needed replacement as well! I complained and said there is something obviously wrong with their parts because I already had it replaced 4.5 years ago! They were not understanding at all. I told them to replace the cable only for now because the cable still had a 12 month guarantee and I would get enough money together to get the pedal replaced during the next year. And guess what ....today 22 October 2015 (3 months later) the cable snapped again! GIVE ME A BREAK!
