Absolutely bad customer service from online staff

This is the second time i am writing a bad review for Rentoza. My phone that i rent from them was broken (due to user error) and needed to be repaired. Rentoza collected my phone a week ago. I was informed it takes about a week and a half, however i needed to find out the status of my repair as I was getting angry that the staff who is repairing my phone is accessing and reading my whatsapp messages. If you are repairing the phone for a cracked screen, why are you reading my whatsapp messages?????? I then emailed rentoza and called a guy name Ceya and told him that I am not happy with this. He said he would investigate. Nothing came of it. Then i emailed for a follow up with Richard. He doesnt even bother replying to my emails. Then this morning I went on the online chat. Was 4th in the line. When i got to number 1 I waited 45 minutes for someone to actually help me. Surely there cannot just be one person on the chat box. Lulutho confirmed this. But I struggled and am still struggling to get ANY assistance from them. Why is Rentoza so slow and why do the online chat staff not taking their calls as they should. If i am number one in the line and there is more than one staff member, why take 45 minutes to come online????????????/ This is really really rediculous.
