Debit Dispute not getting sorted out - Pathetic Service

<p>On 30 September 2016 went with the relevant documents to claim a refund for double deduction for a purchase made in Zambia. The form was completed by an employee at the FNB Chatsworth branch and submitted. On 6 October 2016 I get a sms stating to send a clear copy which was done. 3 times I got emails requesting me to complete dispute form and they are requesting me to give them the correct reference number. Where do I get that from. They should have which clearly shows on the sms. Please can you resolve this urgently. TIME TO RESOLVE QUERY ACCORDING TO YOUR DISPUTE FORM CLEARLY STATES 10 DAYS. This is not acceptable pathetic service. They have emailed me twice back my invoice which I sent to them. What is going on. Unprofessional and untrained staff. Its been 20 days now.</p> <p> </p>
