Unfair Billing By Turkcell

In my May and June bills from Turkcell for my line, I was charged amounts beyond the agreed commitment of ₺410. When I contacted the company, they claimed that the additional charges were due to a game purchased from the Google Play Store. Despite speaking with five different customer service representatives—and noting that my calls were recorded and can be verified under KVKK—the issue remains unresolved. While the company initially told me that my bill would never exceed ₺410, my latest invoice came to ₺873.20. Turkcell refuses to honor the original agreement and now claims that the promised amount is not their responsibility. Each time I explain the issue to a representative, they respond with phrases like “we understand you” followed by “unfortunately,” and reject my objections. It’s clear that the call center staff are not adequately trained, and customer requests are not handled consistently. Each call results in a different response, but always ends with another inflated bill. It feels like they are playing games with customers while quietly adding extra charges. I request that the excess charges on my last two invoices be refunded and that the company take responsibility and resolve this issue properly.
