Customer nummer: XXX

I'm using your internet product currently，I informed you to change my contract from 1000 Cable to 100 cable in Oct 2020，and it shows effectived on your website.

but I received invoice of Jan 2021 (invoice#XXX)， from 22.1.2021 to 31.1.2021 you still charge me with the price of 1000 Cable，pls double check and refund the extra money to me。
Thanks a lot.
