HORRIBLE account access when using new phone

Purchased new iPhone - did not know I would need old phone to transfer my account. When I attempt to log in with new phone, access code requested. Your system DOES NOT SEND it either to my email or text message. Customer service attempted to send a code by both methods - NOT RECEIVED. Customer service is also unable to delete my account so that it can be re-established.Therefore - I have a USELESS doorbell that is linked to a phone that I no longer have that I cannot use to access my account.I have posted a negative review on line so that hopefully others will be able to avoid purchasing this JUNK product.
