REACT ALARMS-WANT MY REFUND

On the 29th December I made a error and paid React Alarms (R 683.50) instead of paying ADT.<br> I only realized this when ADT phoned to say they never received payment. I then had to phone React Alarms & spoke to Mariska, which said i must email her the proof of payment and details.<br> <br> I have now been emailing her since the 01-02-2016, asking when i will receive my refund, but 10 days later i have still not received it.<br> <br> Does React Alarms not allocate payments? What happens to payments that don't get allocated to a accounts? <br> Do they not check with customers when they receive payments like this?<br> <br> I want the payment of R 683.50 refund into my account.<br> <br> <br>
