Your retention agent confirmed the cancellation but she only cancelled one line instead of 2 lines as I requested on my form, the sad thing is that am not allowed to talk to her and nothing is getting done.May you kindly assist pretty please. Your telkom shop cant assist still, they advised that they must send a fax to your retention department, meaning that getting service from telkom is a mission impossible
