I'm closing my Miladys account as they don't care for me!!!!!!!

I have been a very loyal account holder for more than 15 years. Recently I have had ********** activities on my account (since July 2020) where someone is buying airtime on my account to the value of nearly R2 000. I have e-mailed the help@miladys and service@miladys weekly for a month now and have not heard anything from them. I was so desperate that I went to one of your stores on Friday and expose myself to COVID. The poor staff tried to phone head office to help me resolve this but guess what...they held on for 10 min after which I said to them to give up. Really...do you NOT CARE to lose my account?????
