Axxess is Like a Sad EX

So Yeah, I requested for my account to be canceled on the 29th of May 2022. I did not have enough money in my account to pay the R349 and there was no option to downgrade and that is the reason for cancelling(and the Fact That they do not supply fibre in my area(at that time).

I am getting invoices for the month of June 2022 which I did not even use 1mb of. Why must Axxess make it so difficult to leave them? They made me Buy a Router of R1800 for LTE and now I don't have use for it. I already paid you for the Data that I used, so why am I still being Bothered?
