On 41622 I made the order and once I submit the order the
3.00 did not applied to my order went to pick up my order
Asked to talk to manager a young girl said she was the manager when I asked about my 3.00 off she said she does not know anything about it and can’t do anything and have to wait for GM. waited for GM and when he came in he did not
Listen to anything I have to tell him, was very rude said has to go too busy said the 3.00 off for carry out dors not given out all the time. If this is the case then they should mention it
In the TV add. I know that is not the case. Someone should teach these managers that when a customer come with a issue they need to make time to listen not being
Rude and have bad attitude toward that customer.
