Poor customer service experience with True Store Exchange Kuching

I'm writing to complain about the training session I received from True Store Exchange Kuching. After paying $250.80 for unit, I found that it was promised features that don't exist. I've tried resolving this with your customer service team multiple times, including speaking with Johnpaul T., but have not received a satisfactory resolution.
