Very irritated Customer

I was double debited in error on Home Connect end as they forgot to cancel my old address. For the past two weeks I been calling to get a refund with success. I have been **** to by a agent named Sibusiso who assured me that the refund was done but to call and speak to another agent by name of Nomzumo just for her to tell me nothing has been done. There is never any managers to assist.
