******** deduction

I have had a very bad experience with Absa personal loan department. In April they deducted the loan amount twice in my account while I was not in arrears. I contacted them they reversed the other amount, however they deducted again last month when they had offered me the relief due to Covid, I contacted them again and the money was reversed back into my account, after that I have been receiving sms'es that I didn't pay last month, I contacted their customer service they promised to look into it and revert to me, they never did. This month again they deducted twice. I am so frustrated by their customer service. This is the 3rd time I have been inconvenienced by Absa and everytime they promise to fix the mistake only to get the same frustration month end!!!!
