Zero Internet Connection

<p>I have had a contract with Cell C for over 10 years. I have constantly experience bad internet connection and it has gotten worse over the years. I stupidly went and upgraded with Cell C thinking that maybe my previous phone was the problem. At first the internet connection on my new phone was perfect (got the new phone in about November 2016). In the last two weeks, I have had zero internet connection. I have plenty data avaialble but cant use any. I am seriosuly frustated and at my wits end. The last time I complained, i had a member of Cell C phone me and ask me stupid questions like what is my Co-ordinates. Just sort the damn internet problem out PLEASE</p>
