Wrong info sent to me gets my account suspended

I have been a Vodacom customer for approximately 3.5 years. Monthly I receive a statement/invoice and I make payments promptly. The last statement I received was on Feb 11, 2015. From there on I only received sms reminders to pay my account, presuming that they have changed their way of communicating with me. (In this time they also informed me in the same way that my CONTRACT price have increased - contract obviously doesn't mean much). In each case I made the payments and received messages thanking me for \paying your Vodacom account". Through this process and Vodacom failing to send me my monthly statement/invoices I missed part of a payment. The last response I received however thanked me for paying my account May 4). On May 14 my account was suddenly suspended without any notice. I think this is terrible business practice and I think Vodacom can take responsibility for telling me that I have paid my account. Hopefully someone can man up for the mistakes made on their part.<br> """
