Escalated twice still no responce

Good day<br> <br> I queried for a loan on the morning of the 18th of May 2015.<br> <br> They said I should receive a callback within 2 days. After the 2 days passed I called again, they escalated my case and gave me a escalation number and responded by saying I would receive a call within 2 hours. No call was received, the following day I called again and it was escalated again. I still haven't received a call.<br> <br> All other banks I queried at called me within 4 hours of submitting my query.<br> Escalation reference number : ***
