Is Three sharing our contact details with scammers?

[Reducer]

Over the past 3 to 6 months I have received a huge number of calls from scammers in India pretending to be Three. As a three user, this is extremely concerning? What are Three doing to protect customers and how are scammers successfully accessing Three user numbers?

I have been scammed 

I refuse to believe three doesn’t have anything to do with data breach 

the scammer had all my details and sent a text message sent to me in the same three thread from previous messages and emails 

I was offered a sim only deal £3 cheaper than what I was already paying on my sim only but discovered I was scammed when I was sent a handset along with my new sim and checked on my three app where I will now be charged £32+ per month 

I am in so much distress having to contact my bank and cancelling my card and cancelling all direct debits etc 

I have got in touch with fraud team and was told I’ll be contacted within 5days with update and outcome 

I have not heard back it’s now 5th day 

I am disgusted with the handling of this situation. 
I feel I’ve been fooled

Not only I was unable to log back into my three app I’m still receiving texts for outstanding payments etc which is distressing 

it’s now been 5days

India the well known home of on line scammers/ thieves; Pakistan is now rapidly catching up too.
