Poor Service

Hi. I called Telkom Mobile customer service last week Thursday 31/05/2018 requesting for a number change. I was told that it would take 2-72 hours to be processed. On Tuesday 5/06/2018 I made a follow up call and the consultant that assisted me said she will esscalate it to her manager and it would take 24 hours. Till now my number has not been changed and it's causing me an inconvenience. When I call the call centre I have to hold the line for about 20 minutes before a consultant answers the call. They are offering bad service and it's now getting to my nerves
