ABSA customer unfriendly

I am an ABSA client for many years. The ABSA advert on TV about a 13% interest rate on a new fixed deposit account (saw the ad again just now), got me interested and I therefore went to ABSA Walmer Park yesterday to inquire. I had to fall into the customer info line sitting on the hard metal row of chairs for a long time (moving along up and down up and down, to eventually talk to one of the three on duty info desk staff members about this TV advertised fixed deposit account (not knowing where else, or how else to go to inquire about it (as this refurbished branch is rather customer unfriendly, in that everybody working there is in cubicles behind frosted glass panels - behind closed doors - except the people behind the info desks). The really bad part was when I got my turn I was told (in under a minute), that the 13% on this account was on hold due to the increased interest rates. Sorry. The man said he did not understand why the TV ad was still running. I said I was not happy to have to sit for so long to be told what he told me about the offer/ad. This experience was very disappointing. I feel **** to and cheated.
