Poor service from Suzuki

Two weeks ago, I called Suzuki in PMB wanting to purchase a car. I knew what car I wanted and wanted the sales person to begin process. Getting him to get back at me was huddle because he often said they had power outages. Anyway, finally sent the required papers and it took him a while day to get back to me. Once I received the approval form different banks, I wanted them to change the lending interest offered on the deal based on my credit score and other things. Two weeks later, I haven't heard anything from those people. As a motivated buyer this is very disappointing that I now need to go to a dealer that's far from me and have to do the process again.
