netstar is a ****

I would like to express me deepest disappointment with the level of service from Netsar.I initially bought my vehicle in 2021 on October 26.The contract was paid for 36 Months in advance. To my suprise at the End of September 2024 they debited my account and according to my knowledge the first Payment was supposed to go through end of October .On the end of October their debit order went through.To my suprise I get a Call informing me that I owe Netsar R322,I explained to the lady that my contract was paid for 36 months upfront and that I was expecting the first Payment to go off at the end of October and Not September.I asked How is it that I owe netstar R322 ? And I never got an explanation.They then decided to handover my account to collection and are threatening a judgement against my name.Is this the level of service I can expect from Netstar? i was told someone senior would contact me to date no one has contacted me.Instead I get an sma that I need to pay R322.

I am definitely going to terminate my relationship with Netstar as this is broad Daylight *******.
