Old Mutual robes clients

I am an old member of Old Mutual for years, I have policies and bank account with them. This year on my birth day morning, end of May 2022 I purchased airtime and data combo using the bank app, my money got deducted but never received data nor airtime. I thought it was going to get reversed but nothing happened. Beginning of June my mother got sick, got hospitalized and in my state of emergency I used the app to buy data and airtime so I can be able to call the hospital to check on her, my money got deducted and I never received airtime not data again. I went to Old Mutual branch for assistance, got no joy, was promised a call and email, so after a while I made phone calls, sent couple of emails to follow to no avail until I gave up and told myself that I will never use their app to buy airtime again even though it was an inconvenience to me. My mother passed away in July 2022, one of my life policy insurance claim took a week instead of 24hrs as advertised/promised after I had paid the branch a couple of visits to claim. As if that was not enough, at the end of August 2022 I used Old Mutual bank card to draw out cash on another bank ATM, experienced "withdrawal double charge" on my money account. I went to report to two different branches, showing them transactions on my app, the physical slip and bank statements supporting my claim and dissatisfaction. I was told that I will be contacted, I should keep checking and use reference number which I never even received initially. To date I haven't got my money back nor any explanation as to why not, ethic, trust factor and faith between the service provider and client has been broken and I am busy researching other banks right now and I will cancel/close my account with Old Mutual and open a new one with their competitor. After going through all of this within one year, I really dread the thought of going through more issues next year and years to come with this company.
