Checkmygroup review: I want my money!

I registered online in a FB ad for HMRC.

I then received 4 letters from the real HMRC because checkmygroup wrote to them. HMRC was telling me I owe them monney.

In December HMRC send checkmygroup £165 I was told I'd get £88, then I had to wait 28 days, then I had to sign into a link in my phone, I emailed them again and again, then I was told to wait another 28 days. Checkmygroup IS a scam it's all over Google search people like me waiting and given bs. Checkmygroup has UPSET me and the real HMRC can't/won't help!
