Very dissatisfied with the service of Telkom

Im soooo disappointed in telkom first of all they took atleast 21 days to investigate my case of ***** and unauthorized contract taken against my name. Today 04/05/23 i get sent a bill becoz i paid my statement late for March which was 10 days late and paid R7. 00 extra the statement today shows to pay R739. 70...where is the logic or common sense in people to send a statement dont investigate a case of money owing to me and to just send a statement of what i must pay in April. I tell you what i will never pay this bill infact i am changing my internet to Vuma now i have the guys come in already to install.
