I Raymond (Nancy's husband) took a contract with vodacom since 24

I Raymond (Nancy's husband) took a contract with vodacom since 24.10.2022,since then they're unable to give me the specific amount of installment and also do not send me correspondences to show me the information eg end period of contract and also the remaining balance. I did contacted the nearest branch but didn't help. Contacted also the head office and said they will send the information but nothing done as yet after repeated follow-ups. This is really unfair and inconveniencing because nothing is done according to my wish.I expected to finish paying according to my will so that I can move on with other commitments.Im really concerned.
