Refund failure

An ADT salesperson came to do an assessment at my house on 31 Aug as I wanted to have an armed response alarm system installed. I opted to buy the system and was told to pay atleast 50% deposit, which is R1950 on 2 Sep. I subsequently cancelled the application due to dissatisfaction with the service from the salesperson. The alarm system was never installed. I submitted a cancellation and refund request on 13 Sep. Only after contacting the ADT customer services call centre, did I get a response via e-mail. The consultant assured me that my refund request will be submitted for approval. When I followed up I was told that they are still waiting on approval. I called again (23 Sep) and was now told that the refund was approved by the creditors and that it is now with Legal for approval. When I asked why with Legal, the consultant could not give me a clear answer. When I asked consultant to give me a date or turnaround time to work with, this could also not be provided. I cannot think that the refund process for such a large organisation could be so cumbersome. All I want is my refund to be paid.
