Do not upgrade Online - My last Vodacom contract after 20 years

I accepted for number 1) 75 sms & 75 voice for R149 and got 50 sms & 50 voice for R165 I accepted for number 2) 75 sms & 75 voice for R319 and got 50 sms & 50 voice for R336. So I contacted Vodacom again and then the guy told me it is my problem, I must contact customer care. I made 3 requests to get my conversation that was taped but this guy (Neil Subramoney) does not answer my questions or my emails. After my first complaint I was then contacted by Neil and I phoned cust care, and after a 40 minute call the original sales lady (her name is Fanele) joined the call and promised she would phone me back in 10 minutes - it has been 5 days now and she has not phoned me back and Neil is again ignoring my mails. I know where the mistake is, she thought I wanted more data but now they are in quiet mode thinking the problem will go away. And still I have not received my taped conversation. They are showing blatant disrespect to me as a customer. At the moment I have 3 contracts with Vodacom and my wife 2 - when this runs out, I am going to MTN. Do not ever upgrade over the phone!
