Great customer service, etiquette and efficiency

I loaded my phone on Sunday 22/03/2015 with 100mb data, the data didnt reflect on my phone when i checked the balance. i then phoned vodacom and one consultant told me service might be slow but from her side it shows that data was loaded, i phoned vodacom again after two hours and another consultant told me that Vodacom has been having a technical problem since last year and that i have to call them each time i needed to check how much data i had left. On the 23/03/2015 while i was busy browsing on my phone i got a message that data had been depleted. i phoned vodacom again since data from the previous day was not reflecting still, i asked to speak to a manager and was transfered to John Motene who assisted me. Not only was he calm, patient, efficient and humble but he also ensured that i get my data back. John is a great asset to your company!!! Malebo
