Economy Energy, who are they?

We switched to Economy Energy as a result of a search on a comparison site, which showed that Economy Energy would save us money. That still has to be proved. However, I wish that we had never moved. It has been a complete disaster. We signed up on 25 Nov. 2016 and went "live" on 22 Dec. They do not have a website that is fit for purpose. You cannot see your account and all it has is promises of what is to come. Phone calls are not picked up, emails receive auto reply, but often no actual reply. There are promises that the website is being tested and would be up and running soon. Months later, no improvement. We received a statement for our electricity usage (estimated), but they had not included one of the direct debit payments. We received the gas statement several months later. I had been telling them that they had only started taking payments in February - not soon enough. We then got an email in May to say that they would take an extra payment on 31 May. They then took the regular monthly payment one day later on 1 June. We still have no website of any use, no idea what is happening and it is a complete shambles. Avoid at all costs if you value your sanity. We will jump ship at the earliest opportunity.

What on earth is going on at EE.

So many posts on TrustPilot like mine.
I am really worried now.
Especially the random increase in the direct debits for NO reason and when challeged you get so much misinformation/rubbish.
Also told I CANNOT change the direct debit??
:-
I was about to write to the CEO [see CEO website got all the details]
However, I am just staying quiet and pay when bills are due.

I have spent ages on the phone and chat lines trying to sort out errors.
1] Readings for electricity not being saved.
2] Advised no bills for first 3 months then quarterly.
3] Bill received for electricity only after a month. Estimated.
4] Advised will get the gas shortly after.
5] Got notified a new direct debit for gas 35% higher.
6] Estimated yet I am still £72 in credit for gas.
7] Advised new DDR was due to high usage, cold snap [EH! must have missed that] higher than expected bills. Old supplier informed them of my higher than normal usage
8] All completely rubbish and made up.
9] Advised to forget this???
10 ] Advised that EE or I CANNOT CHANGE direct debit. It HAS to stay as it is
10] Advised to wait until bills re produced 25th September.
11] Advised that these will be produced 3 months after I joined as normal.
I am still HUGELY in credit after all this so cancelled DR's until it catches up pay up right away if in debit, then ask for them to be reinstated.
I have now GIVEN UP chats and calls to them as they make it up waste time and do not do anything.

My opinion is that normal methods of communication with Economy Energy will not work. The front office is inconsistent with its responses indicating that its people are either not suitably trained or they are responding to the hour-to-hour whims of their managers.

For my part, I have reached an impasse with its normal customer services frontline operation who refuse to escalate to more senior personnel. I have gone down a formal complaints route, but I am pursuring other measures to seek redress.
