Harassments from Call Centre

I keep receiving messages and calls from Brooks and Luyt for a truworths account for a Mr Thabane. I have since called the call centre and advised them to please remove my number from the system and to desist from contacting me. This morning I have yet again received another call from them. Please could you remove me from you call list as I dont know a Mr Thabane and I have had this number for a very long time.
