Poor service - *********** staff

I have been with Standard bank for over 30 years. While I have not always had the worst service with Standard Bank, I have also not alway had the best service either but I have remained a loyal customer. Today I am furious, I have been into the bank to sign a OTP form to switch numbers. This was something I was charged for and only a portion of it is correct. Some of my information comes to my new cellphone number and others don't. The fact that this was not done correctly should not be my problem to sort out, Standbank should get it right the first time! I called a while ago and a lovely lady said she could do it but it would take two days....well it is still not done. I called again and spoke to Siyamkele and I feel sorry for him having to take the brand of my anger but I refuse to go into the bank to do this procedure again because staff members have been ***********! Why was I told by the last person they could do it over the phone and now I need to go to the bank??? I need this resolved immediately as I don't have access to the other number and I need to make a payment to a new person. I will not be going to the bank again to sort this out! This is not acceptable service and it is the last straw that broke the camels back. If this is not sorted out immediately, I am happy to take my business else where, you have until the end of the working day Standard bank - the ball is in your court now. Signed a VERY unhappy customer.
