Absa horrible service

I'm so disappointed in the service received once again from absa during this horrible pandemic the service is so pathetic I cant believe I'm shocked...i bank with absa and have a personal loan my money was available to pay because tho times are difficult I made sure the money was available absa failed to take the money on 3 occasions after I confirmed it can be taken.... I was receiving horrible calls as if it was my fault I requested to speak to a manager 2 twice and no one ever got back back.. Absa than double debit my account yesterday all in the space of just 1 month I have never missed payments and today I got a message telling me my account is being handed over to MBD and none of this was even my fault.. Im already so stressed daily and now absa is making me out to be a a horrible person yet again all in the space of 1 month when I got the message saying my account will be handed over I nearly had a anxiety attack I'm still trying to calm down
