Bad after sales service and bad manufactured produ

I have bought a brand new Specialized Tarmac Pro frame set at the end of 2012 which costed me R25 000.00. After less than a year I notice a small bubble on my rear stay under the paint work. About three weeks ago I notice the bubble got bigger and decided to take it to the bike shop I bought the frame from. They confirm that the bubble was under the paint work and definitively is a manufacturing problem and the bike was also standing indoors. They forward the frame to Specialized in Stellenbosch which are the suppliers and they said the that paint warranty has expire. The bubble is under the paint and it looks like rust forming under the paint. They are still refusing to replace the frame. I am very upset with the whole situation as the product does not come cheap and it no fault myself that cause the damage to the product. At the end of the day I think it's better to buy the Scott, Giant and other brands as you get better service and value for your money. I will definitely recommend all my cycling buddies and any one look for the Specialized bikes not to buy it.
