SUPPOSED SYSTEM "GLITCH" WRONG INFORMATION ON STATEMENT

i have a D/Credit card. Since moving to Disc bank its diabolical. Saturday 20 June 2020 i saw on my statement that an amount for SpecSavers Key West Krugersdorp had gone through. As well as budget facility had been activated on my credit card unknown to me. i live in KZN. I called DB and spoke to the agent. She saw it on the statement on her side. Said she would send a query to ***** Dept. NO CALL FROM ***** DEPARTMENT> 22/6/202 i call again to find out what has happened to be told by another agent she cant see it on my statement that she is looking at. over and hour on the phone and no concrete resolution. I was told there was a system 'glitch' and maybe your account was one of the affect accs. i am STILL WAITING FOR THE CORRECTED STATEMENT TO BE SENT TO ME> IT IS NOW OVER 4 HOURS LATER. where is the communication from Disc Bank to notify the affected account holders of the system error?????? NO CUSTOMER SERVICE> What confirmation do i get showing that the errors have been corrected????????
