ruuude consultants and billing incorrect again like last year

im supposed to be on price lock but my debit order was for R730 which is supposed to be for R649, i had to reverse it because it was over my budget due to corona virus we are not getting paid, not my bill has shot up to R889 from R649 to R889. i have been calling holding on for an hour each call called 3 times. how much is my telephone bill now. first 2 consultants dropped my calls after holding for so long. 3rd one cant explain why my price lock changed from 649 to 730. she was extremely rude. said its insurance then when i asked can my insurance be r80 she changed and said its last payment. what is the real reason and i want my service connected if not reverse my payment.
