worst customer service to its own clients

the worst after sale service exprience, *** 97017. on the 15 i did online loan application during the process the application was acting up, which i finally manage to complete the application on the 16 and was told to go to branch to do finger prints. when i get to the branch south gate they finalize the application and do a payover however i noticed that the amount paid is less what i am approved for, when i ask i was told i bought tablet, i said no i did buy that, then was told to call head office which i did and was told to call blue label to cancel the tablets blue label said they dont have my details i should call african bank again when i got back to african bank i was told that they will log cancellation request and give me the ref number and i should receive respond within 72 hrs, since then i have never receive any call from the 21 to date i have to call then every day and i am told we still working on the case but no any communication what so ever from african bank. it looks like now that they have me in their books, they dont care to help me as long as i owe them
