DISCOVERY BANK WORST SERVISE EVER!!

Its sad to say this big of a company service is so bad,no its worse than bad.I given them 1 star by accident. Last year March Discovery changed from fnb to there own bank or somghing like that.In that change over they some how lost my details.So they back on my old details old phone number old email address they increased my credit card limit with out me knowing. So i call them numerous times(+30 times not joking)to solve this probleme.IN ALMOST A YEAR NOBODY AT DISCOVERY COULD HELP ME TO RESTORE MY CURRENT PHONE NUMBER AND ADDRESS. They just told me they have to sent it to a certain department and they will call me.Geuss what they never call me.This is the servise you get from DISCOVERY BANK. After 10 month's this issue is still not sorted out.. A really got the worst servise ever from Discovery bank....
