Vodacom terrorising me with sms every midnight

So Vodacom decides to ignore my complaint last week about messages I receive at midnight. Instead of that, they decide to bombard me with more messages at night and a dozen of massages during the day. I have been a loyal customer for over 15 years but loyalty does not mean anything to Vodacom and my complaint does not mean anything too.

I have done my part, this is my third complain. Is it time for to take this matter a step further to consumer ombudsman. I will also cancel every contract I have with Vodacom and take my number to a network where I will be respected. You think that you have the monopoly of the market, no you don't. I will also make it my job to spread a word to my friends not to deal with Vodacom. Maybe you have no idea; a word of mouth is a very powerful tool.

This is my last complaint and I have formed a different opinion about Vodacom now. You are an arrogant institution that is only interested in profit making. You just want me to wake up at midnight and buy data. You do not give a damn about disturbing me in sleep. You bad customer service is really unmatched.
