Worst ISP

When you have a problem you can only deal via email and cannot phone. If my connectivity is down how do I send an email. Eventually sent a mail describing my problem only to be responded to with a cut and paste reply by someone that appeared to not even read my mail as to what the problem was. After that many emails sent and no replies. Eventually bought a new router and fixed the problem myself. Their router is still under warranty so lets see if they replace it.. Now 2 days with no response. Very quick to sign you up but after that you are on your own
