Unhappy with service, upgrade on data gets loaded more than what was agreed without client's consent as per POPi Act and then i get a bill for more than i am currently paying,after i stated repeatly that i can not afford more than i am cutrently paying, i loaded complaint on Friday vi e mail to the customer services no feedback at all not even a phone call or e mail to say the complaint is being attended to, Is this how Vodacom is doing business???
