NRG Centurion - Failure to act with integrity and refund the correct amount due to me

I have had nothing but bad service from NRG Centurion since my lease expired with them on the 31st of August. I was sent a snaglist by the agent on the 4th of September, to which I responded to within an hour with comments on what I agree or disagree with. I even made a suggestion that they deduct an amount from the deposit for these supposed repairs, but there was no response to this.

I spoke to the principal of the estate agency Mary-Ann Mosoeunyane, who happens to be the owner of the property of the 5th of September and she advised that there were a number of things that needed to be attended to and repaired at the property and that she would need to fix all these things before she could refund my deposit. I agreed to this as I had no problem paying for the damages that I had caused. So I told her she needs to send me a quote for the costs of repairing all the items mentioned. I was told I would receive this within two days, but this never materialised. I kept following up with both Mary-Ann Mosoeunyane and the people at her office on this but I was being sent from pillar to post with new excuses every time I phoned or emailed. The contract states that the deposit refund must be finalised within 21 days of the termination of the lease. I followed up again with them after the 21st, and there was still no commitment as to when they would finalise this, or send me a quote of the supposed costs incurred. I decided to escalate this to the franchisor (NRG Head Office) on the 2nd of October, and they promised to address it with NRG Centurion. On the 3rd of October after escalating this to NRG Head Office, NRG Centurion sent me a spreadsheet with a list of things that needed to be repaired/ replaced. There were no slips attached (as required in the contract) or proof of expenses incurred as a result of attending to these maintenance items. I disputed some of the amounts listed, and made comments next to each item as to what I deemed to be a reasonable figure for the repair. This was completely ignored, and they merely proceed to deduct what they wanted to deduct, with no explanation as to how they arrived at these figures and with no receipts or invoices for the expense incurred! Their calculation was to deduct R6836 from my deposit, and mine was that the most they could deduct was R5158, and I provided reasons why I thought this was the correct amount - they simply ignored this with no justification! On top of all this, there is also a credit due to me for the utilities account of R1900. they have also failed to pay this! We are back to square one again where they are not responding to my emails and questions! I have never experienced such unprofessional and dishonest behaviour from any service provider! It’s been an awful experience! This company has broken every possible rule of the TCF (Treating Customers Fairly).
