Poor Customer Service

<p>I bought a 1gig of data on the last week of March as I usually do every moth but it was depleted by the first week of April and i called Cell C to enquire about this and I spoke to Khanyi who indicated that she won't be able to assi me. Then on the 16th of April I bought another 1gig of data and the 18th my data was depleted.</p> <p> I've been using an iphone for the past year and a half and I've never had such an issue ever this is a first. During the day i use WIFI and the only applications i have open are whatsapp, facebook, google chrome and facebook messenger. So can someone from Cell C contact me to explain to me what the issue could be as i'm really frustrated about this and the poor service delivery from Cell C. I don't mind porting to another network but i need an explanation before I do!!!! </p>
