I gave them one of the major assignments. I had 4 days for submission. I explained them the requirements and shared all the assignment files properly. It was a lengthy assignment and I was not expecting it to be done before the submission due date.
They completed the assignment within 48 hours. It was a pleasant shock for me. After carefully going through the quality I wasn't really happy.
I asked them to either get it fix or refund the money immediately as I had no time left to find another tutor.
They undertook the revision comments. After couple of iterations, the assignment came as I expected it to be.
I think I would come back again to use their service. I appreciate their patience and understanding.
