Home Depot review: marble counter installation

I had ordered a marble top for my bathroom counter they told me they would come out December 31 between one and five no one showed up and no one called me I finally got a hold of someone they rescheduled for January 1 between 12 and 3 o'clock when the workers showed up they told us they could not install the countertop as the old one had not been removed ... we had been told to leave the old countertop so they would be able to cut the hole where the sink needed to be with the workers here waiting I tried to get a hold of Home Depot to clear this matter up I was hung up on I was transferred to the wrong department three times by the time I finally got a manager I was pretty upset instead of trying to calm me down and take care of this matter she was very rude she continue to try to talk over me trying to send the workers away and have me reschedule which was not an option she eventually hung up on me and then my calls were no longer answered
The workers were kind enough they went ahead and did the job without any more contact with Home Depot after the workers left I saw a big brown line going through the marble I thought it was just a flaw in the marble it is a crack when I called back to Home Depot they refused to let me talk to a manager or anyone in charge said everyone had gone home it was only 6 o'clock
I feel first of all to make an appointment with me on December 31 and no one showing up was very poor service then not letting me know the countertop had to be removed before the installers got here again poor service ... and when I called to get help with the workers standing here trying to figure out what was going on I kept getting disconnected hung up on sent to the wrong department and then was given a very rude manager and now I have a cracked countertop this needs to be taken care of immediately or I will be canceling this whole order and be expecting a full refund
