Dishonest and unauthorised deductions from my account

If I could give -10 stars I would. This company has took my money and now almost a month later I am struggling to get it refunded. to top it off my account was debited on separate occasions with the same amount s that they have to refund me. My bank requires proof of which Rentoza has failed to provide. I have sent multiple messages as they cannot be reached telephonically which i find awesomely suspicious. Now no one responds to my requests or provide the necessary information. I will NEVER deal with this company again and the saddest part is that I recommended colleagues to them. I have a huge problem when my money is taken from me without any goods or services rendered. If this money is not refunded I will open up a case of theft/***** as i have had it trying to get the proper assistance with my query.
