Pathetic service

<p> 5 September 2016 I completed a cancellation request and requested to be moved to prepaid. At the end of my term 30 November 2016, my number was migrated. After 10am I lost signal without any warning. I was without signal for two days. Eventually I got signal again but not without more hassles. I can't make calls or send sms'. I contacted customer service numerous times but no feedback as yet. I have been struggling with this for the past 7 days now. Ridiculous to say the least. </p>
