Unhappy, disappointed with McDonald's

So I have laid a complaint to hello Peter regarding the service I got from McDonald's and last Wednesday the 14th I received a call from the customer service team from McDonald's who I then explained what happened on the 10th that I escalated. I was then advised that I will be refunded with my money and still nothing till this day. I logged into the chat app where I 1st made my complaint and only later did they request my card details that I sent and was sent a email that they need my bank statement to proof the money was taken. That I have sent and also visited my bank yesterday and they have confirmed that the money was taken and still I'm inconvenienced because if I don't follow up they don't even bother to acknowledge my concerns. I just want my money refunded and knowing that they not even considerate or even acknowledging the fault was on their side and yet expect that I should just accept what has happened and let it go. Firstly I was told the money would reverse with 24hrs and look it's already close to 2 weeks and still nothing.

Will I even be compensated for the awful service chasing and doing follow ups when they can't even respond and advise if they are working on it or not.
