Bad service

Good day<br> After spending a huge amount of time coordinating with work, my partner's work, insurance, the storage company and Eezi Move, my move was set up for 24 June. I sent a signed quotation through on the Thursday afternoon (18 June). It appears the consultant misread my email and sent me an updated quotation (with the same costs etc just more detailed information pertaining to street address and the like). I then signed it first thing in the morning and emailed it off again but thought that was merely a formality as I had already signed the quotation the day before. I have now, at 2pm on Friday 19 June, just had a phone call from Eezi Move saying they are fully booked for the 24th. I am so angry as I had planned my whole life around that date that in my eyes was confirmed. I was told they could move me on the 28th of June but that would be at a more expensive rate as it's the end of the month. Is that really proper customer service after I was messed around by them? When I complained, I was just told repeatedly that \First come first serve"."""
