false information

i took the dstv the one of R 499 price lock and it was installed on the 30/09/2021. i was advised by the guy that was assisting me that i dont need to make any payments as its part of the deal payment will only be made on my debit order date on the 25/10/2021 including the pro rata i was happy since it sounded like a great deal, today my son wants to watch cartoons my DS was suspended due to pro rat no paid i called and they said i need to make payments today with what money coz as part of our contract my debit order date is on the 25th and i was never told that payment will be made on the 15/10/2021. what worst after calling their call centre they sent me an sms advising me of the amount that must be paid they never sent me an sms all along. i am really disappointed for them to give such false information and such an inconvenience , i am thinking of cancelling my contract with them, how can they treat new customers
