Absolutey poor poor service

I have been a standard bank client for 20 years. I recieved a call from a lady working for standard bank stating that my credit card has been in arrears since October 2015. This should not be so since I paid R2000 towards it on 13/10/2015. The lady said she would call me back but has not done so. This is such unprofessional behaviour standard bank! You guys called me to collect money i supossedly owe and the moment you find out it was a mistake on your side you leave me in the dark! Disgraceful! This is the second time that this has happened. Now I fear my credit profile has been negatively affected and even worse I have no control over my transactions. I have not missed a single payment since getting my credit card in 2013 so it is unfair and unacceptable for me to be punished for Standard Bank's own shortcomings. This is just one of many persisting problems that I have experienced and continue to experience with standard bank. I think it is time for me to make a switch to Another bank. I should have done this 10 years ago to be honest. I await a call!!
