holding on for help at call centre

After spending 30 minutes on hold to get a basic bit of help with a pre recorded message telling one that they value your call please be patient etc.... no chance to leave messages I think is very unfair. This call cost me R100. 00. Day light ******* when I am a subscriber this should have been a share call or toll free number. Really guys you need to address this system. I honestly feel that the cost of my enquiry is exorbitant and this call should be partially refunded. I certainly will not call your centre for help in a hurry.
