VODACOM MISMANAGING MY 2 CONTRACTS

Good Day In 2019 I converted my prepaid to data contract and kept my cellphone number A contract account number was assigned, contract no. I***-6 with monthly installments of R209 (Cell no. 1) In 2020 I opened another contract, which was cell, data and minutes and monthly instalments of R689 (Cell no. 2) Due to current COVID hardship I missed 2 months installments on both and both my cellphones were locked for outgoing calls and internet I then paid R1000 on 1st August hoping to unblock cell no. 1 since the payment would cover 2 installments and the balance with pay portion for cell no. 2 This was however not the case as Vodacom advised both contract are on one account which was never requested by me, nor was explained to me. This is not acceptable as these contracts have 2 sims and should be managed separately. I want vodacom to unlock cell no. 1 as this was originally linked to the account no.
