I requested the service at 4/3/2021 and a technician visited and mentioned he needed to order the item. Today is 8/23/2021 and still waiting the part. I've called the customer services since June 2021 and got the same answer continuously. (UNTIL TODAY) Like "could you call back tomorrow (that is, after 24 hours later) so that we contacted the plumbing company." I did call back again and again since June. Then I've got either the plumbing company did not call back or the plumbing company was still waiting the parts. I asked to provide me the time frame to resolve the issue or replace the plumbing company or refund my charge. But samething like a broken record. "I understand your situation, but we could not provide you the timeframe, could you call back so that we could contact the plumbing company". I could see the statements are on manual. It seems like I order "TESLA"
