Bad customer service

I have been put on hold several times to speak to the DIY department and then the phone just cuts. I called in again and again and explained to the switchboard lady that i am not getting any assistance and my call is just ended. I have asked if there was anyone on duty to assist me and was advised the staff is on duty but to my surprise no one answers or receptionist doesn't even bother to ask one of the staff to call me back. Why put up a number phone that will not be of any use to customers. it it frustrating as i am using money to keep on calling without getting any assistance and the lady answering the phone doesn't even wait for me to finish talking. once i start talking she just transfers the call. where is customer service there. i am really not happy. what is the point of hiring some1 ro take calls and they not even patient. Service really sucks.
