Date of Acknowledgement

This is a letter I got from ICICI Bank on 14th November

Note: A scanned/ faxed letter is accepted only if the date mentioned on the request letter is prior to 7 days from the date of scanning/faxing. If the request date and the scan date differ by 8 days, then the request will not be processed.

As per the first line, the date should be before 8th November
As per second line, if it is before 7th November, the request will not be processed
Is this what they wanted to say
Why is their customer care so clumsy
