Cant't Get a Response from Their Complaints Dept

On 26 Nov 2015 I wrote to Carmen Fisher to register a complaint with the bank about the non response from their card division.<br> <br> I was advised that I would be given a complaint number and they would get back to me within 5 working days.<br> I needed the complaint number to register the complaint with the Banking Ombudsman.<br> No reply was received<br> <br> I e-mailed Carmen Fisher again on 13 December 2015, but received no reply.<br> <br> I e=mailed again on 23 December 2015, but still no reply.<br> <br> The matter relates to my credit card P.G. Verkerk ***09 4333.<br> In August 2015 a number of ********** transactions were made against the card.<br> The matter was reported to the bank and in due course monies were reimbursed.<br> There was however a shortfall and I was charged interest on the ********** amounts.<br> I asked for a recon on how they had arrived at the monies reimbursed and was promised that the matter would be looked into and that I would receive a recon.<br> This recon has never been sent or advised and the shortfall persists.
