Scammed by vodafone qatar agent

Hi everyone, I need some advice regarding a nightmare I’m having with Vodafone. I am an offshore worker, and a few months ago, a sales agent came to our accommodation in Barwa Al Baraha. He offered a "special offshore Wi-Fi plan" and explicitly told me:

1. There is **NO lock-in period**.
2. I can disconnect anytime.
3. I only pay for the time I actually use. I never signed a physical paper or a digital contract. I only gave him a photo of my QID in WhatsApp. Now that I want to disconnect, Vodafone is claiming: * I am on a **9-month mandatory lock-in contract**. * They claim they have a **"signed contract"** from me (which is impossible unless it was copied from my QID). I’ve been a loyal customer for 3+ years, but their customer service is ignoring my emails. Meanwhile, a "Retention Agent" called me and told me i can pay for 3months instead of 9months and disconnect the wifi. At first i agreed to this but after sometime i thought to myself that i haven't signed any contract like that and their sales agent has scammed me. I told that retention agent i will not pay for something that their sales agent has intentionally misled me but now he is claiming they have a "call recording" of me agreeing to it (I only said okay because I felt pressured and lied to about the signature). **My questions for the community:**
4. Has anyone has been scammed by these "no lock-in" promises?
5. Can they legally hold me to a contract if I never signed anything? Any advice from people who have fought Vodafone and won would be greatly appreciated!
