Worst service ever and NOT the first time!

I was married and had to change my surname at the bank. This was done at the Pta North branch where I received superb service. I requested my new cards to be sent to Montana branch. I received two sms-es stating that I can collect my cards. After standing in a queue for 45 minutes with my 3 month old baby and my 2 year old, I was told that there is a problem with my pin to be linked to my new cheque card and I must return in 48 hours.I was also told that my card would not work until then.After spending an hour in the bank I had to go home with a card not working.I then contacted the complaints department via the Card Division as *** does not work.The first time I was cut off.The second time I was cut off after leaving my details and cell number but no one could bother to phone me back.The third time I spoke to Kabelo at 16:00 at the complaints department who took all my details.I explained to him that I want to know why the bank sends me a message to collect my cards when my card is not working and why could the problem not be resolved while I was in the bank?He promised to investigate and phone me back.It is now 1 pm the next day and no word! I WILL change my bank ASAP!
