My ISP suxx

I am using the same ISP for over three years — it gives me internet access via cable TV. It works reliable (I had maybe 3-4 moments without network) but they got hit by popular problem — overbooking…

According to contract I have 3072/512kbps connection but during last weeks it is rather 3072/90kbps and it blocks me from sharing of my work with people (how long can you wait to push 40MB file over network?). All calls to their support sounds similiar — “we will contact our technical guys to check what is going on” ;(

Which ISP it is? It is ICP Poznań.
