Edgards bad services

Never in my life have I seen poor services for Edgards head offices in Durban. I have been trying to close my acc since August 2018. I hav been in spoken to the Manager there but now she is ignoring all my calls she gave me her direct line ********** the line is only ringing or she cuts the call, if you phone the call center the let you Waite for like 20mint and then sometime they cut the call or they don’t get back to you, I have been trying to phone each day And yet I get ignore I actually don’t what to do anymore please if there is any advise, I can’t carry on like this for a poor services that Edgar’s is giving me. They so quickly to phone for your money and then they add thing to your bill without any consented and then when you quarry it then this happen I am so so fed up with this..::
