Shocking service from Vodacom

Once again how we get **********. I have been a Vodacom customer for more than 20 years and have had numerous contracts. For the past few years I have had a Red Advantage Package. Due to the fact that I retired from work more than a year ago and monthly haven't used even half of my data and air time allocation. So in the beginning of October I decided to approach a Vodacon shop to get advise on what I could do to down scale as my contract was ending. After lots of consideration I chose a migration to a Smart TopUp package, which I was told would start on 1 Sept 2018. On Wednesday 29 October I checked my balances on my Red Advantage Package and I had in excess of 1GB of Data and in excess of 500 minutes left. This morning, 31 October, I received a SMS notifying me that my Migration Package has been completed successfully. On checking my data and minutes balances, I had zero. After a visit to the Vodacom Shop and a long call to Vodacom Customer Care, I was basically told that that's the way it works and I will have no cellphone use until the 1 Sept, when the new package will be loaded. Customer Care ??? UNBELIEVABLE so my data and minutes for the last day of my Red Advantage package has been taken by Vodacom! So for a whole day, after a great deal of time querying this with Vodacom, I am still inconvenienced, and unable to make calls for the day! They don't really care!
