After using many big named ISPs and then suffering, I came across ABC Broadband.
I was very apprehensive of going with it(after reading so many negative reviews here and other forums) but had not other option as I had already used other providers in my area and was dissatisfied with them.
After subscribing to them, its been around three months now and have not faced a single problem. Either they never had any problems or they seemed to have worked them out.
Its the best ISP for me with affordable cost and FUPs. Hope they continue providing this good service.
