Debit without my consent

Hello Peter

Lewis debited an instalment of R1500 at the end of November as agreed. Next thing I saw another debit on the 11th December without my consent. When I call them they say they sent an sms on the 4/5th informing me that. I did not receive any sms. I am a pensioner and I only have limited funds for certain things. Someone’ deposited money in my account so I can withdraw for something that was worth that amount but Lewis withdrew half that amount without my consent. Where am I suppose to get that money from to replace it? When I call the consultants are not helpful and don’t care about the fact that it is their fault they didn’t send me the sms. They **** to me and connected me to another consultant when I asked for a manager. I have been a loyal customer for years before being a pensioner but they don’t care and **** me for being loyal and even making a stop order.
