Account display as 30days in arrears

On the 07.02.2020 I contacted Vodacom because I received a message that my account QV400771 was in arrears with R52 the agent on the phone said it was a system error but I paid a R60 in any case. When I extracted my credit report Vodacom display as 30days in arrears with R52 every agent I speak to is advising me that it’s my responsibility to contact Compuscan to update my credit profile. This is unacceptable!!!
