Shocking customer service ACDC Richmond

I purchased two Genki portable power units from ACDC Richmond branch through an agent in Kleinmond to power only television and fibre connection. I received them on 16th November and started using them immediately. By the weekend of 26th/27th November the batteries had run down to 2% and would not recharge. I complained to agent who collected units and returned to ACDC Richmond for testing. We heard nothing and agent had been trying to get answers from Latief Karriem who neither responded nor showed any interest in assisting us and they were obviously unable to explain the problem but had no desire to refund us for the units. I took over trying to deal with ACDC head office but was treated with such lack of enthusiasm and definitely no interest in showing any kind of customer care or respect. They continually refused to return my calls. I spoke to Latief Karriem, Patrick Dowling and Tito Silva who all showed the same lack of interest. I requested details of owner / responsible person and was only given the name of Mario but was refused any further information. I want a refund and this has been going on since end of November. We are now almost at Christmas and trying to contact anyone with any say in the matter is useless. The treatment I have received from ACDC Richmond is absolutely shocking and have been shown NO respect in their dealings with me - the little that I have had. I fully intend taking this further and my next step is the Consumer Protection Act. I would fully advise anyone wanting to deal with ACDC Richmond to look elsewhere or be certain that they know the product being sold.
