Unbelievably poor service from Vodacom

I requested assistance multiple times regarding my vodabucks issues and was told that the supervisor would call me back, that my issue would be resolved in 3 working days and if not I should call back… when I called back, the call bot said that due to such a high call volume from my number (because I called so many times to try get my issues attended to), that my number has been blocked. Now how am I supposed to get ANY customer services?! Just ridiculous and unacceptable.
