Inadequate customer service & no adherence to SLAs

I'd emailed the Standard Bank Prestige Banking mailbox on November 17th and received a receipt confirmation with an indication of a 24hour turnaround time to have someone contact me. I received no response and have sent a follow up email on November 23rd. To date, I have still received no feedback on my queries raised.<br> <br> In parallel, I called the call center to eventually get the help that I wasn't able to get offline over email. After 20minutes over the phone I finally received approval on a loan that I was requesting. The agent emailed me the parameters of the loan. I sent through an email response to query some of the deal parameters and to ask for a review of the interest rate as I've been a long term loyal customer. Here again, no response received to my email.<br> <br> November 24th, I called the call center again and was told that I needed to get my assigned Prestige Banker to motivate for a better interest rate on my loan. I got the details and have sent the email through to my assigned banker and 1.5days later I still have no response or acknowledgement of receipt of my request.<br> <br> My recent experience with the bank has been dismal and unacceptable!
