VODACOM *****ING DATA

I use data for a card machine (Ikhokha), last year and up to about 3 months ago 250MB use to last me an entire month. I put on Thursday last week 250MB and only used it for 3 transactions and by Friday it was run out. I can't get hold of a consultant, just one voice prompt to the next. PATHETIC SERVICE, Vodacom *****ing our money and than no service consultants to answer the phone, we as consumers just have to accept speaking to a computer... I hope Vodacom will get back to me and let me know where my data is going to.
