Day 2 of no service from Smarty

Despite Smarty having taken the fee for the provision of a mobile phone service, day two sees me with my account still paused. This means I can make or receive no phone calls, no texts to other than iPhone users and no effective phone service. This is now becomeing very serious. I have made a formal complaint twice, copies of that complaint emailed to Smarty customer service and complaints in previous posting. Being disabled makes this a living nightmare. My sister has visited me this morning as her usual phone call to me could not be connected. Smarty customer service 'chat' seems incapable of assisting. They offered me a phone number to call but I cannot make phone calls! I seriously wonder whether now is the time to seek assistance in closing down my account with Smarty and going with a proper service provider.
