Dissatisfied customer

Completely dissatisfied with their telephonic services. Been phoning them since half past 2 with no answer, it's officially 3:25pm and someone eventually answers, I asked them if they still have of the Big Jim 30L tubs available as I would like to put a few of it on hold until I get to the store. They person who answered said she will have a look, she forgot to mute the call, I can hear her having a fat conversation with her colleagues and all of them having a good time, was waiting for almost 2 minutes and then they just hang up. I called them back, no answer, only after the 3rd call again, she just says sorry, doesn't even ask anything and then transfers my call and it rings for almost 4 minutes with no answer. All I wanted to know was if I can put of those tubs on hold as I was going to drive to Kenilworth from home. Very disappointed in them.
