Urgent confirmation needed

I have contacted Vodacom numerous times. A number was removed from me profile since it was not my number. I had to get a affidavit made prior to wait to state this number is not mines and I do t have the Sim as well. This has turned into a ugly matter whereby I have been requested to provide confirmation from Vodacom that this number which was removed is not mines. It was removed within 6 weeks, thank you and refunded. But I need a letter on a letterhead stating that I only have 2 contact numbers and the numbers removed is not my number. I have been to the stores for this letter, I have asked numerous times but received emails only. I require a valid Vodacom letter plz. This is my life and reputation on line for this mistake Vodacom made. Please can this be fixed for 2020
