The customer service is completely awful 1- authentic team just sent the measurement with a picture. I asked for further checking. No one replied but kept asking to confirm. I have no choice but to use my eyes to verify the pattern. 2- once I clicked the confirmation, they said they will check further for me but again no checking (and kept claiming that the bag is confirmed). If this is the case, why ask me again and again? 3- seller promised to send me the branded dustbag and they HELD the dustbag and gave me a BROKEN company bag. I then asked what’s happening and again they said it’s not in the description. They kept asking me to confirm the receipt of the bag and then shifted all responsibilities to me with NO reply. 4- cs staff said I understood you but no more helping and said this is the best teaching materials. Who cares to the teaching materials? If you wanted to experience this servicing standard, please continue :)
