EFT Reversal Bad service

On the 29th of July I requested an EFT reversal of 4500 which I had paid to a bogus Landlord whom at the time I believed to be a rightful owner of the apartment I was supposed to rent. I made the EFT around 2pm on monday. I requested the reversal on wednesday morning before 8:30. I was given a refence number & told to check the progress after 10 days. On the 11th of August I got a message that the matter has been resolved and that I will be contacted with the details. No one contacted me. Soon after that I got another message with a new service request number opened . I then called the customer care line on the 20th of August & was told that they will escalate the matter & that the consultant who made the request will send me a form that was supposed to have been sent the day I requested the recall. I waited and still no form was sent. I called again today 21st of August & was referred to the presite line. Not much help there either, just promises of them sending the recall form which I still havent received yet and that the matter will be given a sense of urgency which it was supposed to have received in the first place. All hope of getting my money is back is gone. Very Upset
