Cancelation due to death

What do I have to do to get decent customer care? I went into the shop in Garden Route Mall, took my husband's certified copy of his Death certificate and I. D. This isn't easy, still mourning the loss, but do what must be done. I was told 30 days, this was the end of May. Phoned at the beginning of June, nothing on the system, email documents, have a reference number. Phoned again, a week later, nothing on the system, email the documents again. Phoned when I received this month's statement billing up to 8th August, nothing on the system, email the documents again. Why? This is a devastating time of loss and pain, each re submission opens the wound of pain and loss. Each and every person I spoke to was so reassuring that This time they would ensure the contact would be canceled, only to be left with nothing being done. I'm at my wits end, my husband's bank account has been frozen, dealing with each and every closure is still so painful, but ineptitude like this is unacceptable. Telkom you need to do some serious upgrading in your customer care. I wonder if by making this public I may get some response. I'll wait and see.
