Poor treatment of customer relations

I had a very bad experience with Vodacom the last time I spoke to a call center operator. I was trying to reactivate my line after it had been suspended. When she let slip that the line had been deleted AFTER I had paid my arrears, I questioned her and she refused to answer my questions, eventually putting the phone down in my ear. I got a prepaid sim and I've been using that with a smile on my face. No effort was made from Vodacom to attempt to contact me after this, despite me having a perfectly working email address that they send me documentation on a regular basis each month. This morning I got a bill of nearly R14000 which I have threatingly been told to pay within 21 working days 'or else'. Let me make it abundantly clear how insulted I was on a personal level by your staff and your farcical company. I want no further dealings or debt with you clowns, so I am willing to make an arrangement, but you need to contact me, and since your customer care is so fecal in quality, I have to complain here to get your attention. Your staff *****ed up, deleted my number AFTER I paid arrears, told me to pay more and I no longer have a contract as a result. Who treats people this way?
