Poor service at Vodacom

They were supposed to open my line after a missed debit order, I paid via banking app as advised but took me more than 24hrs to open the line. They said it take 2hours. I called multiple times. I was told they have a problem with their FNB costumer so I must email Mr Tshabalala a team leader in the collections department and he will assist me immediately. I am still waiting. They don’t even take their twitter account serious because I have left multiple inboxes. This is my 10yr with Vodacom having a 5th contract but I am not happy
