Bad Customer service from consultants and team leaders

I'm extremely disappointed at the service that I got from Vodacom customer service. The call centre department is the "repeat call" department where u get out through when you consistently call. So my airtime kept getting missing and on the 15 of November I thought I had the issue sorted out. It then happened again in the 19th and the airtime was of the highest necessity at that time. One agent told me that they could refund me where as the other one told me that they can't. So I'm thinking the training they receive should be the same and they should be giving us answers that are uniform. When I asked to speak to their Team Leader I was told that they come in at 8am before the lady hang up. When I called in again I was told that they come in at 10 am only to have their team leader Lindiwe call before 8 am. So their agents have a tendency of lying and to add to that they just hang up the phone. They also give their colleagues the phone to impersonate being their team leader. They are rude, they cut you when you talk. They even go as far as finishing your complaint as if they know why you calling. The people I spoke to are Nomfundo, Tshepiso, Lerato just to name a few and they are all in one team led by Lindiwe. I can fully understand why that team is acting this way judging from the fact that she promised to send me a recording and even set a time for me to go to a Vodacom Shop where she can send it to me, till now no follow up. I've been complaining about not receiving smses on my phone and till now the is no help. They telling me to buy a new SIM card when they sold me a faulty SIM card. I don't know if it's their way of driving up sales. I've been using Vodacom for over 20 years and I'm absolutely disappointed. I've been buying all my handsets at a Vodacom shop and I must say I've wasted my money. I honestly didn't want to write this review but after I called on Saturday the 22nd and yet again was promised a call back by Noxolo in the repeat department l, I've picked up a trend that Vodacom doesn't care about their clients. Even her team leader said she sent an email to Lindiwe and as you might have guessed no calls today. So I'm changing my network to MTN I heard they have a better service.
