Netstart has no clue

This must be hands down the most *********** group of customer service people i have ever had the displeasure of dealing with. During Covid i cancelled there service as not required, last year they claimed to not have received my request and started threating me with legsl action, at first i thought it was a con but later reluctantly agreed to pay. They claimed everything will be sorted last month i again received a call for outstanding amount, i spoke to lady and they arranged the cancellation, today again i get a call from them for outstanding payment. I would encourage everyone to never ever do business with this organisation as nobody knows what is going on. Now in terms of TCF they have done everything in there power to stop me from cancelling the plan as i cannot believe an organisation is so ***********.
