Ryobi RM 1800 lawnmower blade

In good faith I purchased a RM 1800 lawnmower from Takelot at reasonably good price.The product is light and flimsy but for the price worked ok. After 1 year the blade is worn out. Now nobody in SA is able to pass the Blade to me in East London South Africa.The company says I must get it from a mower centre in east london.the mower centre says they don't stock it and it not in stock in Stevens and co PE and they don't have it on order. The blade is stuffed and dangerous and nobody in PE or East London has any stock your agents want to charge me R 600 to buy it via courier. I am disgusted that in this modern age u expect consumers to by stock via 3rd parties.if you stock the core item on Takelot why the &#$55ck is the blade not sold there as well ? So for #$uck sake tell me where in SA east London can I get the RM 1800 blade replacement ?
