Cell C
Epeated calls from 084145

I keep getting calls from 084 145 and when I answer its just music and then gets cut off. I've already had 6 calls today and even if i don't answer, the call just goes to voicemail and leaves me a long message of music.
I understand this is a cell C service number. I don't want to receive marketing calls from Cell C, let alone marketing calls where I am in a queue instead of actually speaking to someone! Please stop these calls.
