Overgrown wasteland

I reported this issue last year and nothing was done despite being told that this area is cut twice a year. I have lived alongside this waste land for 5 years and have seen it cut twice! This area of land is waste, it was once garages which have been knocked down and left to despair. My back garden runs alongside one of the boundaries. The grass/weeds/foliage is left to grow 6ft high. It grows into my property under and through the fence. I have peered over the fencing and people have also fly tipped on the land so god knows what kind of vermin live amongst the filth. I know this land has NOT been inspected by the council as the entrance is completely overgrown!! I can send pictures if needed but I highly suggest action is taken soon. Thanks
