Non Existing Service from International Prize Winning Bank

I recently sold my house in Moreleta Park and app**** to FNB for bridging finance until the registration process was completed. I submitted all the documentation including the guarantee nearly 4 weeks ago. FNB Private Bank confirmed the receipt of the documents and proceeded to approve the application. The bridging finance is for 43% of the selling price which complies within the banks funding bracket. I received an email from my private banker on 4 July confirming the application was approved and the issuance of the document and loading of the facility onto my account would be completed within 48 hours. A week, later and after many phone calls and emails to the Private Bank, I am still waiting for the issuance of the document to sign. I have been in contact with the DM of Private Bank who sent me an email on Tuesday morning confirming the issuance of the document was imminent. I inquired as to the meaning of the word imminent to which I have not yet received an answer. I received an email from my private banker on 10 July at 13:13 confirming I would receive the document within the hour. I have STILL not received the document. My emails are no longer being answered by the 3 people I have been trying to get an answer from. I have NEVER received such bad service, never mind from a bank that once received an international award for being the best bank. I have decided to put my complaint on Hello Peter because I am getting nowhere with FNB. I would have preferred to keep this in house but i have been forced to make the poor service received from FNB made public and hope somebody from FNB will have the decency to be honest with me and give me accurate feedback.
