Consistent Poor Service and Lack Thereof Provided by Vodacom (only capable of dropping customer service calls)

I would give 0 stars if possible. This is not the first issue I've had with this service provider but will definitely be the last.

I called vodacom last week to cancel my contract however the agent persuaded me to take out an upgrade on my contract. A week later I follow up on the delivery of my device only to be transferred back and forth from after sales to upgrades. The last agent says she will call me back in 30min with feedback. 2hrs later no feedback, I call 2 more times, my call is picked up and left to waste my airtime the first time and dropped immediately on the 2nd call. I then post to facebook. Shortly after the agent calls me and apologizes for taking long due to systems issues. She then tells me the quote on my upgrade has expired as no one from vodacom called me to confirm and that I have to undertake the whole process again, which took 45mins the first time. I asked to be transferred to cancellations which she did. And my call was dropped again before I got through. I called cancellations directly. The agent took my id number and dropped my call. I am waiting for someone to contact me from vodacom to cancel all my holdings with them as all they have done so far is waste my time, money and airtime going around in circles. I will no longer subscribe to a service provider that is unable to actually provide a service. I would not reccomend vodacom and their ability to complete queries is below average at best
