We use several backhaul providers, including Zen Wholesale. Though not mentioned during the order process it's no secret. Had you asked, we would offer the information freely.
The problem here is not the backhaul provider nor the ISP.
You have an ADSL2+ service (expected speeds of 1-3Mbps down, upto 1Mbps up) You are receiving 6Mpbs down, 0.8Mbps up but are uploading large video files which saturate the upstream causing the connection to grind to a halt.
We have gone to great lengths in calls and emails to demonstrate this to you, the Support Manager has reviewed the case. The chosen service cannot support your level of usage. You are not tied to IDNet and are welcome to try any ISP for FTTP. The information provided is factual not aimed at making money from you.
We always empathise and work closely with those incapable of carrying out local tests.
We have never mis-sold or deceived you. At no time have you been abused by any member of IDNet. After the lengths we have gone to support you, we are deeply offended that you would make such a claim.
Feedback provides a valuable opportunity to review our performance and we go to great lengths to ensure all at IDNet maintain our high standards of excellence. Reviewing your case for the second time, I remain satisfied the Team carried out their duties in an exemplary manner and followed correct procedure.
Sincerely,
IDNet
