Poor communication and long waiting period for dishwasher part

I am extremely disappointed with the service I’ve received from Hisense. In July, I enquired about ordering a door lock for my dishwasher. I was told the estimated arrival date would be the 31st of August.

On the 1st of September, I followed up by phone to confirm if the part had arrived. I was assured that I would receive an email update by the end of the day. No email was ever sent. The following day, I had to call again, only to be told that the estimated arrival date had now changed to the 11th of November.

I find it unacceptable that I was not updated about such a significant delay and had to repeatedly follow up myself. Furthermore, I do not understand why a basic part like a door lock would take more than four months to arrive.

This experience has been frustrating and disappointing, and I would like an explanation as well as clearer communication going forward.
