If your chlorine readings are right, you should not let people be swimming right now. Not only are the readings sky high, but if they are right (and I doubt that they are) that would mean that you have a CC reading of 14!) Those numbers can't possibly be right. I don't think the pH of 8.8 is right either. You can't get an accurate pH reading when chlorine levels are high.

Until your kit comes, please go to Walmart or the like and pick up a cheap OTO/Phenol Red kit (yellow and red drops). It will hopefully read to 5 but some only go to 3 on the chlorine side. But, you can force it to go higher with a dilution method described here: Testing Without a Good Kit

Then, repost with the numbers you get with the OTO kit. I'm not too confident in your pool store ..............
