I wish I could give zero stars, or minus five stars. I give 3 months studying, 570 GBP, plan a trip to Ankara, Hotel, schedule annual leaves work programs and what did I get in return. Pearson Sabotaged my exam with your test center mistakes, took 15 minute of my time, didnt add this, couldnt understand or accept their fault, doesnt answer to emails or feedbacks for MONTHS, ignore me and after 4 months of review gave me an answer TOTALLY IRRELEVANT and NONSENSE, doesnt even have any connection of their mistake or my complaint. The worst company ever in my life. Hard to get worse then them.
