Unacceptable service

I really had a very bad experience with Rentoza. I ordered a washing machine in the middle of May . I was told that the ETA was the 3rd of June. When I phone on the day to find out when the order would arrive, I was told that there is a delay at the supplier and that it would take 4 - 6 weeks. Weekly Iwould get the same message from support saying the same thing that there is no ETA and they are working on a resolution. Week 5 I got an email to say that there is still no ETA and I decided to cancel the order. I requested the refund on the 11th of July and on the web it stated that it takes between 3 - 5 days to process. Today is day 4, as the refund was only processed on the 15th of July. Today I was told that they have challenges with their refund system and the money would reflect next week. This is after the refund was already processed on Tuesday. They seriously have a problem with their service delivery systems. The emails are the same, so I think robots are managing their payments and support platforms. I would think twice ordering from them again.
