Review on Get Hoppin' With The AppleRound Space Hopper Ball: 28In/70Cm Diameter, Kangaroo Bouncer And Air Pump Included! by Hesham Peltier

I have a situation and would like to share and ask y'all a question, looking for more of an opinion I suppose. So here it is. My most favorite toy in the 70's was my "hippity hop".a big red bouncy ball with a handle that you hop on. I bought one and put it away for my grand-daughter when she was 2. I got it out about a month ago because she is now tall enough to use it. I was ebay one night and happened to discover that now days they sell adult sized hopper balls, so with my new found svelte self I bought one! I thought "oh what fun to hop around the house with my g'daughter!" Not to mention great exercise. .So I looked for the one with the most 5star reviews and it is supposed to be able to hold 300 pounds. I weigh 170.4 as of this morning. It came on Monday, the 10th of November. I have used it approximately 6 hours in the past 2 weeks.(about 30 minutes at a time is all I have worked up to). My home is VERY clean, all hardwood floors, except the baby's playroom, which we had carpeted in March, to cushion her falls. Last night she wanted to bounce with Grammy, I had not been on it for 2 days. I started bouncing on the carpeting, and the next thing I know "BOOM"! I swear the explosion rocked the ceiling! It threw me about 2 feet, and I landed on the floor. It was so loud my son and his wife came running from upstairs, as I laid on the floor covered in busted rubber. My 4 yr old G'daughter was nearly hysterical. "Grammy's hurt, Grammy's hurt". I was sure my left leg, and or hip were broken. After I calmed down my husband and son were able to literally pick me up off the floor. I soon discovered nothing was broken because while the pain in my hip, lower back, knee, and calf was nearly unbearable, I was able to walk. Sleep? Now that was a different story! There was no getting comfortable last night, and no amount of advil, aleve, tylenol, heating pads, nothing was helping. Around 11PM I called AMAZON, and told the girl what happened, she apologized profusely, refunded my money, and told me she would be contacting the manufacturer, and someone would get back to me. Now I am not a "sue happy" person, but this thing is rated for indoor/outdoor use, and for 300 pounds! I am in a ton of pain, and on disability for a blood disorder and auto immune disease. I tend to get staph infections very easily, and you would think under these circumstances someone would have been in a hurry to contact me! I only have Medicare, and if I go to the ER or my Family doctor I am gonna have pretty expensive co-pay, and I am sure they will want to do ex-rays, give me anti-inflammatories, etc.It has been 24 hours since it happened, and the pain has increased. I have aching, burning, and as the night progresses walking gets more difficult. I just took an Epsome salts bath.but I don't think I will sleep again tonight. So what would you guys do? Here are the pictures of the ball.you can see it didn't split on the seam.it literally just blew apart!
