Ridiculous Service Recieved

My mum is 54 and I am adding her onto Fedhealth's medical aid scheme as well as my 15 year old sister.<br> I have sent the application on the 22/01/2015. Renisha was assisting me at that time, my email stated all docs sent please confirm if all is In order, No response received. I then called her several times could not get through, when I finally which was after a week, she advised me I need to get a letter confirming where the debit order will be going off. This was sent on the 27th, firstly she did not have the decency to respond telling me that she needs the letter.On the 3/02/2015 I sent her a mail saying that I called for you twice yesterday, hope you received the messages I left please call me. No response or call returned!!!! I called on the 5th Renisha was busy so I spoke to Valenteen & asked for her assistance instead, they needed more info from the doctor, so I mailed her the info on the 10/02/2015 and then guess what NO RESPONCE! I called last week and Valenteen said she will check with the underwriters and call back but she didn't, I called 5 times this week and the both of them were not available left messages no one has called me, I am FRUSTRATED WITH THE SERVICE.
