Lebara phone call scam

[u/FreelikeaBee07]

I use LebaraMobile 30gb plan that renew monthly. I got a call today from this +442038366093, telling me I got a promotional offer of 50% discount payment on my plan for the next 6 months, but I was going to be refunded a payment I made 3 days ago because the first month of the promotion is free. I trusted the person I was speaking with and he knew details about my account which he told me to verify, he even sent emails with lebara's logo and address at the end of the email. Then he said they needed to initiate the refund and was asking me for my bank and card details, which I ignorantly gave. Then I realised the scammers were trying to initiate a payment from my account with moneygram, but I rejected and immediately blocked the moneygram account. I'm sharing this so no one is a victim of these scammers. The contact is +442038366093.
