"not response from screen, possibly faulty digitizer"

I guess, but it might also be the liquid damage all over the inside of your phone, too.
PS. Calling the touchscreen by the more technical name digitizer didn't help at all, did it?

"Reading that memory card is damaged, gives option to format it, but will not do it. Re-formatted it through laptop but phone still reads as damaged SD card when its not."

I'm afraid stomping your feet and declaring that your SD card is fine did not work. Hint: the problem is not the phone. It liked all my SD cards just fine.

"the phone does off with an alarm sound, when the customer doesnt have any preset alarms"

For this special case, I jotted down and here repeat the case notes that I put into the system for this phone:
Three alarms were set on the phone. One, "Alarm", was set for 16:59 on Tuesday, occurring once, and was inactive. The second, "Alarm", was set for 09:00 on Friday, repeating weekly, and was active. The third, "get up u lazy gitt", was set for 06:50 on all weekdays, repeating, and was active. Alarms have been removed.
