Money hungry vodacom!

First off I would like to start by saying that this company is the worst network I have delt with that I can say is almost the worst now in South Africa. Vodacom has now taken it upon themselves to bill me R100 due to the fact that I payed my phone bill a couple of days late. I can admit from my side I was wrong as it was supposed to be paid on the 31st and it wasn't paid on that exact day. Okay I was a few days late but I PAID for it. I ran into some issues and I was promised my money would be in my account but it wasn't in my account due to issues at my work place. Vodacom has been harassing me non-stop with phone calls, which when I answer there is no one on the other side. Now Vodacom I will NOT pay you a fee for a slightly late payment because no one has been refunded for the data losses from your side as well as the constant issues from your side. Not too long ago my phone stopped receiving calls and data (this was before my late payment) and I could not figure what was going on so I had to take time out of my day to resolve a 'network' error on your guys side. Could I please have R150 for petrol to get to your offices and another R300 for the hour I lost having to sort out an issue from your side. Best network in SA......please stop lying. I will definitely be cancelling my contract when it ends. All you people want is more and more money but give less and less service. I wont have it. Either you sort it out or you can cut me off and I will not pay for no service. Up to you.
