useless network and useless call centre agents

I have always defended Cell c as a service provider but lately dealing with your client services agents has left a bitter taste in my mouth. I called today to increase my limit. The call was within 11h00-11h35. I spoke to some ***** who kept me on hold for over 7min just to increase my limit. When she came back to the phone she didnt bother to tell me why she kept me holding for so long let alone apologise. When i complained about her keeping me on hold for so long and asked for her name she just put me thru to the customer survey to rate her disgusting service. Why do u have such ***********, non caring, unprofessional people working for u. I need you to listen to that and tell me if thats the kind of service you pride yourself with. I also need you to reprimand that agent because she clearly doesnt need or appreciate her job. She is not the only one, I called on the 1st and your agents didnt wanna help me(listen to those calls). as soon as they heard I was irate i was put thru to the customer survey or they hung up. You are also overcharging me and i want to change my tariff. I dont receive statements. i want a formal apology regarding the disgusting service by your useless agen
