Bad Customer Service and Attitude

I have tried to upgrade my phone at 2 different Vodacom stores in The Glen Shopping Centre. After being told that I have been migrated to Vodacoms new 3D system, without my knowledge. The branch managers told me that they cannot assist me as their staff has not had the training to upgrade phones on the new system, I will need to go to Midrand or move to another Service Provider. The latter suggestion was noted, when trying to phone the Cancelation/Retention line 10 times, calls were dropped each time. I have never experienced such bad customer service and bad attitude from staff. You would think that being a customer of Vodacom's for 16 years, you would want to retain the business.
