Refund request

My daughter was playing Homescapes and clicked on purchase a pack for $1.49. Over the space of about a week she purchased another one $1.49 a day and a couple of $2.99 packs. Ok, approved by me to a total of around $35. Problem is, our home internet and mobile service was being worked on, on and off, for a period of about 10 days during this time. She would purchase a pack, the store would freeze, no response or update then the purchase would start again. This happened for the week. I just got a bill for over $200 for what turned out to be 119 purchases of $1.49 and 8 purchases at $2.99. I accept the bill of $35.84 for the 8 x $2.99 and 8 x $1.49, but I won't accept another 111 x $1.49 (total $165.39) when the purchases were not done properly. How can I be charged an extra $165.39 when my internet was up and down like a yoyo and therefore starting a new purchase each time it connected? I contacted them to make a claim to be told it doesn't fall under their guidelines. That is BS! I have been ripped off by $165 and can't do a thing about it. I've purchased an iMac, two MacBooks, iPad, and two apple watches in the past and that loyalty means nothing. I am ropeable!!!! How can I get my refund?
