Mobile - when does month start?

[#1]

Wondering at what time the billing month starts? Mine is 21st of month, but, on my latest bill, I've been charged for out of plan data on the 21st - surely, it should have reset to zero on 21st, but at what time? Data usage was in the late afternoon?? So I've ended up with quite a substantial bill, as it was counted on the previous months data?? Initially , there was an acknowledgement of error and a 2GB add-on provided to get me through month, but that appears to have been changed and I've now been billed for additional data - hence opinion of PlusNet has plummeted from glad they've acknowledged the issue to where's the number for tesco Mobile !

Any thoughts on the timing of month end?
