BAD EXPERIENCE MACDONALDS

I buy almost everyday from Macdonalds and have ongoing problems. I purchased meals on the 20 August, they had network issues and double debited my account said it will reverse which it didn't it's the 27 August I call and still haven't refunded. I purchased again to receive garnish on my burgers. I ordered 1 burger meal hot charged for 2. Im so fed up with Macdonalds service.
