Can’t get a security code via tsxt

[Lauren_A]

I haven’t been able to receive calls or texts and have noticed that there are no bars on my phone. I’m trying to login to see what the problem is but as I’m disconnected I can’t get the security code to login. 
I changed my contract recently but should have unlimited calls and texts still. 
I got my last bill yesterday but it hasn’t come out of my account. I last paid on the 22nd April. 
what is the problem and what can I do please?
