Inappropriate time for a call from Cell C

Goodday Cell C. I received a call from someone at yout company at 19:10 regarding my contract and phone. Firstly, this call was not during business hours, but during my family time. Secondly the call agent spoke too fast and unclear for me to hear her. I asked her to speak slower which she did but I still could not make out what it is she was saying. She mentioned what I am paying and also what handset I have. She also asked if my id was the number she read out. Furthermore I didn't know why she was calling and she simply hung up. I am sure the calls are recorded so please chech the call records for that time made to my number: zero eight two four one six six six two seven. This person must be reassigned because she is not suited to the position of call agent.
