Lack of help, failure to return calls, disgusted

I used to be a Nashua client with a Cell C contract, unfortunately we were forced to become a client of Autopage and i am extremely unhappy. I recently renewed my contract and went onto the unlimited call package. I received an email to say that i had exceeded the threshold, i immediately contacted Autopage Cellular and was told that i was being incorrectly charged for calls and that the dispute would take 2 weeks to sort out, i said that i could not wait 2 weeks as i run a business, Mercy Radebe then proceeded to put the phone down on me when i asked for the turn around time to be quicker. I then received an email this morning to say my phone had been soft locked, i had to get to a landline and call, i spoke to Dudu Myapi who said she had lifted the softlock and i could use my phone and that she would get Lebalang Tema, a team leader to contact me to handle the billing dispute. I never received a call from her and unknown to me my soft lock was never removed. I then contacted Autopage again and was told by Thando Mhlanga that the managers are very busy and i should expect to wait 24hrs for a call back, even though my phone is my biggest business tool. I am so unhappy with service
