Hybrid collections demanding money for Netstar

My partner keeps getting phone calls from Hybrid Collections on behalf of NETSTAR saying that he owes them money. He cancelled his contract with Netstar last year August as he sold the vehicle that had the tracker in it. Every month they keep debiting his account & he keeps reversing the payment so now this Hybrid company keeps phoning him to tell him that he owes them money. Netstar actually needs to give him a refund of R398.00 for 2 unauthorized debit orders for January & February. I have sent numerous emails regarding this matter & nobody gets back to us & nothing gets resolved! This has been going on for almost a year & It is extremely frustrating as Netstar has not done their duties to cancel the contract & just keep debiting my partners account every month & demanding money for a vehicle that he no longer owns. This "service" is actually disgusting & will never refer anyone to Netstar!

I myself have just cancelled my contract because of the terrible service! I've been driving around with a unit that was supposedly "outdated" as they were not able to receive a signal from my vehicle for God only knows how many years & nobody informed me of upgrading my unit, so I have been paying for a unit that doesn't even work & putting my safety at risk. Absolutely shocking service!!!
