Playing the blame game

Been with them for quite a while now. Activated 10Mbps service almost 2 years ago, but since then the line Sync speed has steadily declined.<br> <br> So much so in the last 3 weeks that it is only capable of running at 5,2Mbps - that is 62% of the supposed 8,7Mbps that the line should be running at - yet they still deducting the full amount each and every month for the 10Mbps... - that is f.r.a.u.d!<br> <br> But as always, sending email with sync screenshots and speed-test results, the poor connectivity is blamed on my side of things - DO NOT TEST MY PATIENCE!!<br> <br> Their last email blamed the \... Intermittent Connectivity issue ..."(where on this earth did they get this from?) on equipment connected to my network at home. So running out of excuses"
