Poor service

What does one have to do to get help from this company? I logged a dispute sometime in November last year, got a ref number after weeks of calling. Someone called me to say all my credit information has been updated but later when I logged on to check I found that everything is still the same on compuscan and up until today I can't get credit anywhere. I've been trying to call and email for months and no one has got back to me or answered my calls to date. This is really frustrating
