Unhappy customer

I requested on the 1st of April for a woolworthers personal loan credit increase via the app (that they always promote quick and easy) then received a message they need payslip and bank statement which I sent, then my surname changed which I sent....it took 11 days and I got an increase on store card which is not what I wanted oh and apparently I'm Mrs Du Toit not Mrs Assante I'm so disappointed in the service day 12 today and no help...something so simple!
