Press #4 pushing from pillar to post

I phoned Cell C customer service Centre as I need a settlement letter from them having cancelled my contracts in February 2017 but on my credit report still shows that I owe Cell C money for these 2 cancelled contracts. I was advised to phone the retention centre on ********** and press option 4. If I press option 4 I go back to the customer service centre. So I phoned again and decided to press option 2 to just speak to someone who will be able to assist me. Operator advised me to speak to the legal department to get a settlement letter. Operator gives me the same number to phone ********** option 4. So I advised the call agent if I press option 4 I go back to the customer service centre. Call agent said he will transfer me. Phone call is answered by a lady, I ask is this the legal department she says no I will transfer you. Getting transferred and holding on for ages with no help. Also ********** is not a free number
