Impossible Customer Service/Accounts at Vodacom

On 4 October 2021 we upgraded our contract on-line. We received confirmation confirming the package and the monthly amount. Within a few days we received the new phone and watch which was part of the new package. On the 26 October 2021 the old debit order went through our bank account of R558.99 and on 26 November 2021 the debit order went through again for R558.99 we presumed they would adjust to the new amount of R1048.00. Then the calls started, we receive an automated call from Vodacom every day saying we have not paid the account and to speak to Customer Care. When we phone customer care they say the account is up to date and to speak to accounts. When we try that , which is also automated, we are told to speak to Customer Care !! Customer Care have tried escalating our query and they come back saying we have to speak to accounts. We have emailed and that received replies that we are up to date, then the next day we receive the automated call saying account not paid. No-one seems to know what they are doing at this company. So frustrating !!
