Poor Service

I am paying my mother’s DSTV subscription every month and yet her service is disconnected. In August she was told that her premium changed from R280 to R318 because she upgraded while she did not upgrade. Her service is disconnected again while we paid R318 since October and she is told she owes R240. The first lady we called said she didn’t pay her February premium and we told her we paid end Jan on the 19th for that. The second lady now tells her she joined insurance and needs to cancel it. My mom did not join any insurance with Multiple and this is such an inconvenience and unnecessary stress for someone old like her. Please sort this out
