incorrect billing and flagging account as in arrears

In October 2017 i went to Vodashop Savannah Mall to renew my cellphone contract . Vadocom instead of renewing a contract upgraded my other number. I realized this on the 1st of November 2017. Notified vodacom they promised to correct the error. In the process of correcting Vodacom they upgraded my other number . Went back and complain, they promised to correct, but up until to date they have not corrected their error and that has an effect on credit status. They say i owe them three thousand rand, but my contract is flexi R200 and flexi 55 respectively. upon inquiry i was adviced that i owe them migration fee. i did not request for migration, i only requested that they correct their error which they have not corrected to date .

Today i called Vodacom Spoke Delie Call ref : ********** 282 she basically said i must pay and they will refund. I never budgeted for that amount and i cannot wait for them to refund me after 14 days. She told me that i either pay or my account will reflect as in arrrears even if they are aware that i do not owe them. i have been with vodacom for more than ten years their error and their system should not prejudice me.

Is their error and solving it should not create problems for me.
