EDCON - exceptionally poor customer care and product knowledge

I am extremely disappointed with the financial services offered by EDCON. I called their call centre requesting my 12 month (20.25% interest pa) be changed to a 6 month interest free account going forward, as I do not mind if my installment increases - I am rudely told that it is not company policy to change from 12 month account to a 6 month account, when i asked how had my account become an interest bearing account in the first place the consulted had put the phone down and ended the call. I was not given a reference number however I was asked to key in my ID number which can be used to trace the last call. I have been an account holder for 9 years now and notice how poorly the financial services in EDCON has become. There is a monthly service fee of R23.00 - which could not be explained by the consultant - apparently its to keep the account active but offers no consumer protection etc. Please contact me urgently regarding your policies - EDCON as a brand seems to be dissipating and poor customer service is definitely a point to note.
