Would give 0 stars if possible, they just give me a solution COPIED (even not the same question) from the internet. WORD BY WORD! And they refused me for my refund quest.
The first solution they provided is from source question 5 on page 7.
The second one is from the source example 3. 5. 1 on page 57.
After I provided them the evidence they dare to claim that it just SEEMS SIMILAR! I have tried to solve this with them but their attitude is disgusting! Even I have told them they have no right to make money from copying from online resources. They don't care about it. They don't care about whether this may ruin your academic career. All they care about is how to steal money from your pocket!
