PLEAE PLEASE DO NOT USE THIS COMPANY!!!!!! PLEAE PLEASE for those who are looking to join this company as there supplier. DO NOT UNDER ANY CIRCUMSTANCES. I have only been with this company 7 months. Iv always paid quarterly and wanted to do the same with this company. Greenstar where happy for me to sign up and after that I heard nothing. I kept submitting meter readings to keep my usage up to date. 2 months in I kept calling them to advise they don’t have my bank details and they advised they will call to take my details. 3rd month in no bill received and no bank details taken. I called customer service advising I have no bill and you don’t have my bank details. I am now over 6 months in and they finally generated a bill and expect me pay for this. They apologised it taken them 6 months to send a bill as oppose to 3 months I am now left with a hefty bill and have logged a complaint with them which I am still waiting to hear back from there complaints department with a resolution. They want to put me on a payment plan which I refuse because I am fine paying every months 3 months NOT 6 monthly. Especially when Iv been chasing them for a bill!!!! I have been informed this has been an error and they have had internal problems with generating bills. I want express to those please do not join this company I been given the run around to date they have ploughed me into debt, I have a outstanding bill over £1000 that’s need be resolved due to there error and no one from there side is take responsibility, what a Shocker, NOT. Once my case is resolved I will closing account and going back to a repeatable company like EDF or British Gas. I Iv notices other people have been treated the same way and I have and hope this company gets what’s coming to them as they cannot treat customers like and think that’s acceptable!!!! Their customer service and complaints team are based in Milton Keynes but you can only speak to the customer service team which is a waste of time. They can be contacted between the hours of 8am-10pm on 08000124510 should you wish to try!
