no contract ****

so I have been using Rain (4G package that is off from 6 pm - 11 pm) since July last year if I am not mistaken, we have had our good times (free unlimited deal during certain months) and mostly bad (poor connection when it rains and when its windy). however, at the beginning of this month (October 2021) on the 3rd, 6th and 9th I have been calling and email them trying to tell them that I no longer want their internet service but they have be send me from pillar to post and I thought it will be easy to do since one of their selling point is no contracts involved but they told me that they will cancel my subscription in November the 1st 2021 since its postpaid. 1. to me it means there is no contract selling point is not true and also if it postpaid is the strategy why do they charge me until the 3 of October because that's when I told them that I no longer want their service then that will be a fair postpaid or cancel my service and charge me till the 11th because I won't be able to pay them this month that is why I told them from the 3rd of this month that I no longer want their service but they want to paint as a bad person who does want to pay and thy want squeeze out the little of the money I have.
