Very Poor After Care Service

I am currently experiencing the worst customer service from Netstar tracking company it's horrible and the worst part is that it's involving my money. I canceled the contract on the 8th December 2023, I was transferred to Their collections department namely Hybrid to make a three months debit order arrangement to pay the cancelation fee they took my banking details and confirmed to debit monthly on the 1st for three months starting on the 1st of Jan. They never debited my account on the 1st of Jan when I called they changed it to 1st Feb 2024 to my surprise The whole amount was then debited by Netstar from my Standard bank *** on the 1st of Feb 2024, then 2nd Feb 2024 R600 debited by Hybrid in my FNB account. I've spoken to Palesa from their finance department was polite and asked me to email she will escalate the matter however I am now getting numerous calls and sms's from Netstar that I owe the R1900 and demanding that I pay. I spoke to a lady called Onica from Hybrid who had very poor telephone etiquette and didn't assist me.
