Poor service

I've been trying to transfer my late father's DSTV account into my mother's name. After numerous emails I eventually got the correct form to complete which I did.

I've was informed today that the change of ownership was completed today. Then my mother's DSTV was turned off. My mother phoned DSTV to find out what's happening only to be told that the account is still in my late father's name.

How does that happen? You told me that it's been changed yet it hasn't.

Please do what you say you have done.

How many calls and emails must we make and send before this is resolved?
