Smart Bro (DSL) Sucks So Much

I HATE SMART BRO! Now they're refusing to answer my emails about my complaints of intermittent and slow (80 kbps; thats kilo bits, not bytes, per second). I get about a total of two hours of connection in a day and at a very slow speed at that. I wonder what happened to my connection because a month ago it was working fine. I had an average sustained speed of 384kbps and I was loving it. Now, I get zip.
