Exact Store and FTI Law Debt Collector

FTI LAW who call themselves debt collectors are still sending me SMS's indicating that I owe Exact Store. I dont have an account with Exact store and this is getting on my nerves. I'm gonna report this in TFG platforms cause it's not being resolved. Their email returns and their telephone is unanswered. Stop your sms's, I dont have an account with Exact Store and don't owe you a cent.
