no contact

I am totally disgusted by the service I get! We have been customers with dstv for 16 years, we are trying to upgrade to the explora. We have two subscriptions, I sent a message last Friday to complete the upgrade and to your credit you guys called back and we managed to upgrade 1, the lady then told me that they close at 7 and could she call me back on Monday at 10am to complete the 2nd one, this didn't happen. I then sent a second message on Monday evening, I was called on Tuesday morning and I was walking into a meeting. They scheduled a callback for 6pm that evening again, no call. I subsequently sent another message on Tuesday evening. I called your call centre on Wednesday evening because nobody had called me and the gentleman who helped me gave me another number to sms and assured me that within 48 hours someone would call me to complete the upgrade. I am now going on for 60 hours and have still not heard a word. It is pathetic to say the least. I work in a customer service industry and I can assure you if I gave this kind of service to my customers I would have been called in for a disciplinary..
