AVOID BUT THEY WILL GO AHEAD ANYWAY AS THEY DON'T SEEM TO CARE IF YOU HAVE AUTHORIZED THEM OR NOT!!!!!!!! If I could give no stars I would. Made an online enquiry, didn’t sign anything or agree to anything, then got a letter from HMRC saying i'm entitled to £216 rebate and that the cheque has been sent to this company. Explained I had not authorised Gateway Rebate to act on my behalf. Have been told I have to take it up with the company. Gateway Rebate won't deal with me on livechat as I did not have a reference number. Clearly I haven't as I have not asked them to act on my behalf. I managed to get hold of them on the phone and the lady that answered said only Jack could deal with my query and he would call me back, she also said that they had got verbal consent during a phone call which I dispute as never spoke to this company on the phone. That was 3 weeks ago and no phone call.
