cell c = HORRIFIC NIGHTMARE

I received a sms during the last week of December that I have been upgraded. I never asked for the upgrade which is in fact a down grade as my 100 minutes are converted to R100 (ON MY OLD PHONE by the way). I went to an outlet to convert to a pay-as-you-go since I wasn't ready to entertain the upgrade. They referred me to a call centre because of the (unilateral) upgrade. I am still traumatised by the kind of conversations I have had with those call centre people! In short, each one refers me to another as his/her department doesn't handle such. I resorted to email to voice my frustration, but all I get are more calls from those people just telling me that someone will call me! It has been 4 weeks since I started engaging cell c to cancel that contract as I did not request it and I don't want it. I suspect that maybe I have been speaking to machines as there is no way people with brains can treat a customer this way for so long. Ever heard of customer centricity cell c?
