Instagram Ad Account Overcharged More Than Approved Budget

On my Instagram account “madamenevo,” where I run advertisements, I have been regularly charged more than the approved advertising amount. For each campaign, I am billed at least ₺30 and sometimes up to ₺100 more than the budget I set, and this has happened multiple times. I started running ads at the beginning of 2025 and have so far been overcharged by more than ₺600 in total. I have reported the issue to Instagram customer service several times, but each time I received the same standard response claiming that this was normal, with no actual solution provided. I make all my ad payments by credit card, and this issue occurs in every one of my ad campaigns. I request that the overcharged amounts be refunded to me.
