I want my phone line released into a holding pool - data is already cancelled via online portal

Please HELP me. All i want to do is cancel my data and release my line so I can FINALLY move to a new "SERVICE PROVIDER" Starting when I go into your Vincent Park branch to be told they all offline last Friday then days in a row I have been phoning 10213 and told to phone 10210 then told again to phone 10213 (I have spoken to Subrey, Nontobeko, Nandipa and others that I cannot recall). Finally i got someone who told me to cancel the data is done online - which i then proceeded to do. I then get told to release the line into a holding pool i need to speak to the sales department, so i call this morning and speak to Mandy who said that is also done online, I explained to her I was told to call 10213 to release the line, she put me on hold to find out and the line cut, I am not on the line again and have been waiting AGAIN another 15 + minutes for one of your consultants to answer the phone to have my line released then I get told to call 10210 again. Please can your staff know where to direct a customer first time around and please can somebody assist me?
