Capitec allowing unauthorized transactions

Capitec is annoying, and useless, unauthorized est R400 was deducted on my account 15/05/2019, I disputed and there were suppose to call me, they didn't, I called them, in July and this is the email they sent to me,

'' As per our telephonic conversation, please sign the attached dispute letter by 27 July 2019.

We can proceed with a MasterCard Chargeback which requires you to sign the letter and send back onto this email.

Your account would then be credited with the disputed amount and the chargeback fee of R150.00 would be charged.

The merchant would then have 45 days to provide evidence against our dispute.

Should they not provide any information, your account would be credited on the 46th day with the R150.00 fee.

Should they provide evidence holding you liable for the charge then your account would be debited with the disputed amount and the fee would not be refunded.''

To date I have never gotten my money
