worst call centre - Do not know what they doing

i got my telkom line cancelled 2 months ago and i wanted my landline ported to mweb .

Telkom advised that my line need to cancelled before can it ported . When i called the cancellation department they advised that sales can place the number in holding pool, I have called the sales department which advised that i need to call cancellation department .

all i want is number to be placed in holding pool .. who do i call .. no department wants to take accountable and responsible ..
