Based on a telephone call, with one member of the company, I wouldn't say they made you a firm promise. It's not in writing and unless you've got a recording you can't hold them to it.
I would suggest the member of staff gave you an estimate of how long it would take and they may not have been in a position to properly do that.
You're also not accounting for lags in the system, when did they actually get your order, on the day you placed it or has it gone via some middlemen, or sat in someone's inbox because they were on leave, etc...
and as you say you've not skated for some time, another week or so isn't going to make much difference.
