Bad service - False Promise

Hi, I was called a week ago by Devonika in the call centre informing me that I can upgrade my Telkom cell contracts. I went thru the whole process she advised me that my lines have now been upgraded and that I will receive my new phones and sim cards in the next few days. I only received one upgrade! then phoned the call centre to find out what's going on they informed me that only one line has been upgraded...this is absolutely poor service. After confirming everything giving me my new cost for both lines and confirming several times on which packages my line will be and on which package my wife will be. unacceptable!! it seems like there is a competition in the cell industry of South Afrika who can provide the worst customer service... I have tried on several occasions to get a hold of "Devonika" each time the call centre says they will pass the message to her superior and her to get back to me without avail.
