Stuck with M1 until 2016-02-09, since we were connected after 3+ month delay due to OpenNET 'capacity issues' on 2014-02-10.
Using http://hackerspace.sg/ as an example.
Locked into a recurring two year contract. We tried to switch but M1 said we renewed per contract which as a Hackerspace we were unaware of (until it was too late) and we can't get out of. To compound the issue, we are unable to upgrade from 100Mbps to 1Gbps IIUC until 1 year has elapsed of our recurring contract.
