Contract Upgrade

Contract Upgrade has been a mission and a nightmare with Cell C consultants as I'm now paying for 2 contracts and arrears thou I only have 1 contracts with cell C. Cell C consultants are now saying the UPGRADE I was suppose to be doing was turned to a NEW CONTRACT and they don't have the recording records as they don't know which store called me. WHY MUST I SUFFER FOR A CONSULTANTS MISTAKES? I have been calling from January 2021 and getting transferred to all departments am not getting any assistance with reference or case numbers ***, ***, Case *** and *** yet they say they is only 1 valid case. I am not willing to pay R463 for a sim card I am not even using. I am fed up with Cell C and need this case need to be resolved as I cannot pay for 2 contracts.
