i have been with vodacom for more then 10 years and never seen such poor service!!!<br> <br> I have received the second time/month in a row not the correct data bundle, i am suppose to get 1GIG every month but for the last too months i only got 500MB when i called vodacom last month about it they said no sorry the data bundle is correct and i have used 500mb ( not a mb more or less) in a couple of hours while i was asleep checked my balance again this morning sins its the 1st of the new month again same balance 500mb phoned vodacom this morning just after 8 to logg n service call to sort our the incorrect data bundle (service request number - S3-87D1D-DQK82) received a sms to say my account has been allocated with a 1GIG promo, after i phoned vodacom again to clarify that this is the missing data from last month and this month i was told that i must pay for this 1gig promo... <br> <br> No body gave me a call to explain to me that im getting a 1gig and sorry ASSHOLE you have to pay for it as well meaning im paying for 2gig data but only received 1.5GIG .<br> <br> What kind of service is this? VODACOM IS *****ING FROM ME AND I'M SORRY BUT I'M DUE TO UPGRADE AND ITS NOT GOING TO HAPPENED!!!
