Broke the promised bonus classes without contacting me in advance
First I have to say Thanks to Teacher Mrs. Gao, her patient and vivid instruction keeps my grand daughter eager to learn without getting bored... I would've rated for 5 stars just for the teacher... But with the selling representative Mr. Zhang, I was so disappointed with him that I purchased for 100 classes plus bonus classes before Chinese New Year, and tried to pay in full, but ran a problem with my credit card... Ended up I paid in half for 50 classes with bonus classes, and promised him to pay another half later... Mr. Zhang did contact me for my another half of the payment and I missed his call... I thought people in China they were taking long vacation during Chinese New Year. So I reached out to Mr. Zhang and tried to pay my another half of the payment on Feb. 13. He was about to accept my payment but mentioned that the extra extra 10 bonus classes are no longer available, because it was ended by the end of January... Mr. Zhang had never mentioned it to me at all that I had to make my half payment before January. I would pay it if I was notified in advance. Anyway, my point is that if your representative promised to a customer for your offering, your company should keep your words, otherwise just state your rules via text messages that customers can follow them... Instead just said the offering is ended... So disappointed and angered for what I encountered with Mr. Zhang.
