Harassment

I keep on getting messages from these idiots stating I owe them money.

They messaged me again and I don't even know who they are.

Ignoring Communications. Pay R9672.8 owed to Computech Credit Services Pty . FNB Ac 62319854164 Br: 250655 Ref:COM010948307 CreditIntel Tel 0129400140.

Can something be done about this because this is getting ridiculous.
