Horrible service, contract ended but still getting invoices 👎👎👎

If there was a 0 star I would use it. So this company expects people to rent their products forever and they think people have money to play games. My rental contract was supposed to end on the 1st of March this year. I send out communication and confirmed this with one of their staff members, I have all conversations on email. I paid as usual at the end of February for March and according to previous communication I was done with the rental. At the end of March, I got an invoice for both March and April and email's threatening me that they will come and take their unit which I am done renting at that time and also that they will put me on some ******** list for non-payment. When I queried this, I was told that my rental is a month in advance now so I should have paid on the 25th of March for the 1st of March. I spoke to one of their consultants and I agreed to pay their one month only that was left- end of March. I did that now at the end of April and a few days later I got an invoice for May. You guys need to stop this, take me out of your system. To think I was considering renting another unit, atleast I have seen how teljoy operates and I am not making that mistake. I do not recommend Teljoy at all, they are ******.
