GREEDY!!! Quick to DEBIT, send invoices, force people to adhere to the contract YET VERY SLOW TO TERMINATE

I have been trying to cancel my tracker with netstar the past 4 months and absolutely nothing has been done, last time I called I was told systems are down and I must send an email, of which I did and still nothing has been done. I adhered to the three years I had to stay with the tracker for.

I have taken it upon myself to reverse debut orders from netstar and blocked them as I will not be paying for a service I no longer want nor need.

I just received an email about an invoice, talking about Sars, I did not read it as I am not interested, what I am interested in is for this company to stop these debits, remove my name from their database or whatever system they use. I have kept my end of this contract and as the 'loyal' customer I've been I expect the same treatment, this is absolute nonsense and if nothing is done I will take this matter forward, I will not have a greedy company ruin my credit record
