In an industry like credit repair, reputation is everything when choosing which service to use. In that regard, Pyramid comes up short. To find out their track record with the BBB, we had to find them under their alternate business name, Credit Concierge Services LLC. The BBB lists that business as "NR" (No Rating) status until more data comes in; when we found that listing, there was only one review posted and it was negative. We found just over four dozen mostly-positive reviews specifically for Pyramid around the web, but in an age where we know that customer reviews can be faked (unlike what you find on TopConsumerReviews.com!), it's hard to know which ones are truthful without trusted validation like the BBB.
If you find information that is incorrect, you can file a dispute. Remember too, that items on your credit report that you don't recognize could also be potential signs of fraudulent activity — someone working to secure credit in your name for their own use. Make sure you're clear on items that could potentially be fraudulent, versus those that may simply be inaccurate.
