Cell C's processes are shocking

So I'm back here again because half a job was done. After having our phones blocked from even contacting the call centre, a very efficient consultant responded to my original review. I requested to switch to "pay as you go" since our contract had expired in September. He managed to unblock the telephone line and I can now load airtime and make calls. While I'm at home, my wifi provides me with the relevant data to use my usual social media platforms but when I'm away from the house, I cant message anyone for help. I've loaded data to no avail. So now what??? The consultant only did half a job. How do we get full services on pay as you go? I cant perform my job 100% if my data is blocked. What will my line management think if I cant respond to colleagues on the company's group lines?
