I purchased PDF format of EMC DEA-1TT4 test. They guarantee that you will pass or they will refund your money 100%. So I appeared at the exam and got surprised. Only 14 out of 60 questions came out of their PDF that was probably also stolen from other sites. So, I failed and wasted $69 for DumpsPedia's PDF and $220 for the exam. I reached out to DumpsPedia and told them I failed. I needed my money back and also told them that there were many question in their PDF, the answers were totally wrong. They fooled me by giving me some stupid policy and never refunded my money.
Not sure where they run their business from. If it's US based, they should be monitored for their legality of running this unlawful business.
Be careful before purchasing anything from them.
