Shocking MTN service at call centre

I need to add BIS to my existing contract number, as I need to use my blackberry for a month. I called 1555 and was forced to hold for about 20 minutes, after which the operator told me that I could not just add BIS to my contract, but that I had to go to a store and fill in forms. I told them I could not do this as I will be in hospital for the next few weeks, but the operator simply said there was no other way and they could not assist. I asked to speak to a supervisor, but as always none was available. Now I also have a Vodacom and 8ta contract, and confirmed that on these networks all you need to do is call the call centre and they activate BIS immediately, no paperwork required. MTN your treatment of your customers is shocking, it's no wonder you are losing your subscriber base in South Africa. I will be informing all of my freinds and family of your policies, maybe you will be more flexible in future.
