Reliability issues

I am running into significant sync issues with this program. Not all of my messages that I recieve on my phone actually arrive on my computer. Also, when first opening the program after not having it on in a while, often it will not sync messages from the time that it was off. Occasionally, messages will not send through this program. I contacted support a while ago and received an automated reply and nothing else. Also, even though the description mentions the customization of messages (including backgrounds and colors), this is not listed as an option anywhere within the program.
