STOLE MY DATA TWICE

I bought 1 GIG data on ********** 1 on Tuesday ********** 2 my data had depleted. I didnt know that Vodacom had a data issue because i never received any communication from them. I called Vodacom yesterday and spoke to a girl named Sihle at about 18:06 pm she told me that I would be reembursed my data within 3 working days and in the meantime to buy a small amount of data. She also assured me the problem had been resolved. I followed her instruction and bought 100 mgb only to wake up today with no data again. I had to call Vodacom again and hold for 20 minutes to be informed that no the data bundle issue hadnt been sorted out. A very nice lady named Nicole lodged a query for my number for my missing data. My issue is that im yet to receive a message informing me that there is a data issue. Vodacom service is below par yet the data is very expensive. What exactly are we paying for? I am highly annoyed and I am definitely switching to onother service provider.
