Number changed without my consent

I requested for my prepaid number to be changed to my contact number as I didn't want a new number in Feb when I took out the contract, I was told it would take 48-78 hours it never happened

On Saturday 9 April I went to Telkom mall of the South regarding this matter and was told because my prepaid number was previously with another network they need to log a case for me. I have had this number with telkom for more than 4 years so I didn't really understand but I told them its fine they can log it because I don't want 2 numbers.

On Monday 9 April I was called to confirm if I requested the numbers to be changed I confirmed yes. A few hours later I realized my prepaid number has changed. I tried calling Telkom on Tuesday but failed to get through.

I called again on Wednesday 13 April and spoke to a Busisiwe who than logged another case for me regarding the number changed that was done without my consent. I called Telkom a few times after that to follow up but got different feedback every time. I am so disappointed in the service I am receiving from Telkom because now my whole life is turned upside down, I can't do banking because my number was changed.

Can someone from Telkom please give me proper feedback and resolve my query
