Frustrated by the contact center lines

The quality of builders Warehouse phone at their contact center is so poor one could hardly hear anything the consultant is saying. Since yesterday I've been trying to follow up on the delivery of the online purchase but it is a struggle to hear the contact center. Today when I made another attempt, when the consultant answered the first question I asked was: "did any of you escalate or report your lines" guess what? I did not hear her response, the level of frustration I am in at this moment is beyond explanatory. worse part, the consultant placed me on hold as she claims she was gonna try to find out about the delivery, I held till the phone went mute on me, whilst yesterday when the consultant said will put me through the store, as she transferred me? it hung up!...how great is this again!
