I'm not sure what's happening but after I press "1" to connect the call, it rings once then the call ends. I've tried it on two different phone numbers as well, over 10 times, over a period of 1 hour. It just refuses to connect the call. What is happening?

Could be a technology glitch. Contact the MSP ASAP and let them know what is happening. Also, contact iSecretshop and inform them of the situation. This way, you may not lose points or have your shop declined by the MSP by reaching out to them.
