Poor service

<p>I bought a course last week thursday 2(6 May 2016) through Groupon. the Course name is NLP and the service provider is e-careers. the promise me that i will recieve my course infomation until three working days.... Its the 03rd of June now and i haven't recieve anything. i think they are so unprofessional. i was even thinking of purchasing more courses from them but i'm a bit sceptical </p>
