HORRIBLE EXPERIENCE TURNING INTO AN ONGOING NIGHTMARE :-(

I have experienced bad service before but RENTOZA is the worst a mistake I regret everyday. I have bought some items from Rentoza but the company blocks devices and deduct installments for devices that I bought years back I have certificates of ownership for them but RENTOZA still deducts and blocks them. To a point where they send people to collect FULLY PAID devices saying they are outstanding. I send numerous emails and Whatsapp (CAUSE THERE IS NO CALL CENTRE) and every time the agents respond with random responses as if they haven't even read my emails then after weeks they stop the deductions and unblocks the devices only for them to repeat it again around every payday. WORST MISTAKE! Latest **** is asking me to pay a buyout of R17000 whereas previously and during the begining of the subscription the buyout was R50 now. When I ask them to send me the buyout payment link because I have completed my subscription they say it's R14000 with 35000 still outstanding I ASK and I ASK and I ASK WHY they say no sorry its R17000 I ask again why and how did we get to these amounts (from R50) and they said theyll investigate.. I have been waiting for a response and guess what RENTOZA is still deducting for a subscription (my account is on negative because of the bank charges) that I completed in January 2023 already and the devices are all locked including a iPhone 8 I paid for fully and have a certificate of ownership since 2020. If there is anyone that knows who can assist me to end this nightmare PLEASE PLEASE I cant with this anymore They do not even deserve the 1 star horrible unprofessional ****mers :-(... this has to end at some point
