I am so frustrated right now...

I wish I never changed to Telkom and I wish I never app**** for a contract from them!!! Trying to get through to their call centre is a waste of time... Called 10:50, was answered 11:10 and transferred a couple of times and told to call 10123 which does not exist... figured out it should be 10231, called 11:20 it is now 11:29 and I am still holding... My reference number for the previous UNRESOLVED complaint is SM150781... All I want now is to cancel my contract application and a refund on the monies deducted from my account ASAP. Please if anyone calls me, don't tell me you will get the Online Sales Manager to contact me. I want to speak to the correct person to process my cancellation and refund my money, no one else please. I am so agitated and frustrated now, it has been a week and nothing was done. I need this done today so that I can change to another service provider. By the way, it is 11:34 and I am still holding.... Hanging up now...
