My experience with Asia Pacific Broadband Telecom:
The deal was for 999NT plus around 1000NT for the install and the first three months (so 333 per month). We got the bill for the next three months and it works out to a little over 800NT per month. No one ever told us that the monthly payments would go up. It is not stated in the fine print on the back of the initial contract.
I realize now I was naive to believe that 333NT would be the normal per month charge, but again, things were never made clear to us. I think the present rate is fair, and still cheaper than what we would pay in the US. I just don’t understand that way of doing business and treating customers.
