Bad service

I called in to cancel my contract and the cancellations department took my call, As my contract comes to an end in July, The consultant convinced me renew my contract and eventually I chose to do the sim upgrade because of the great service at the time, well that was just to close his sale. He informed me that my data will be pro-rated and that as of the new month my installment will change, to my surprise there was no data given to me ,so I called the call center was transferred to 3/4 people who were not able to assist me, then eventually transferred back to cancellations ,the lady said to me that the data was not reflecting because I still had data on my phone once the data is finished the pro-rata data will be loaded ,which up until today has not been loaded ,every time I call I keep being transferred After 14 years of being a loyal client, this is what I have to put up with at vodacom
