Changed mobile number not authorized

Over a month ago, my mobile phone number was changed without request or authorization. Spoke in store and on phone with mobile support over 15 times for at least an hour each time. Spoke with store managers , mobile escalation team members, supervisors and tier 3 support. My phone number has not been restored and have been without my phone line. Secondly, I attempted to purchase a new phone requested by an in store associate in case my phone was the problem. I purchased a phone, it would not connect to my phone number and the associate said he would lock my phone in store safe and come back in a few days when my number was restored. After 10 days I went back, in the mean time spoke to mobile support maybe 3 times. Store associate said he returned my phone and refunded the money he charged. Phone is still on my account and cannot be taken off. I’ve spoke to in store manager about this secondary issue, phone support and so on and so on. I need to speak with a district manager or someone who won’t shrug me off like the associates in store
