Frustrated with MicroLab Networks Rio de Janeiro's lack of response

I'm writing to complain about the training session I received from MicroLab Networks Rio de Janeiro. After paying $130.14 for plan, I found that it encountered rude staff. I've tried resolving this with your customer service team multiple times, including speaking with Leopoldo N., but have not received a satisfactory resolution.
