Very very poor company and mistreating customers

Iam so disappointed on this tracking company I wouldn't recommend anyone to join it. My account was handed over to nimble group for not pay for two months!!!.. Just two moths!!! Can you imagine iam so shocked even now.. They don't even call you AND asked why payments are not made, they don't even do follow up. This netstar company is just not fair... Well it's fine I paid the R340 that I was owing and account is up to date but still nimble group keeps on sending massages... NETSTAR PLEASE TELL YOUR LAWYERS NIMBLE THAT PAYMENT WAS MADE ON *** AND THEY NEED TO REMOVE MY NAME ON THIER SYSTEM PLEASE!!
