Vodacom Ruined me

I was offered a contract with vodacom telephonically on the 20th of May 2019 on my cellphone ***, then following day i called for follow up then i found out that the data was allocated to the wrong number which is ***. i called and cancelled the contract same day 22nd May 2019. Recently when i was checking my credit score i noticed that they listed me on credit bureau. last month i called trying to resolve the issue of which the matter was resolved, i had to go to vodacom and pay R54.00. Later i called applying for the contract to right number but i was declined, then i tried MTN then they told me vodacom listed me i must solve the matter with them worse part i need data contract as data is expensive what do i do because i was told to wait for 90 days.
