I was charged five times making a ten dollar payment for wow , wifi hotspot

I ordered the $10 unlimited Wi-Fi through xfinity.Now they ran my card and was cool.I got my Wi-Fi well.I looked at my bank statement, and within 45 seconds of me, ordering that $one0, 4 more $one0 charges came from xfinity now Wi-Fi.Now they were all pending banks can't do anything until they're , you know , process , blah blah blah , so they process the one that I actually made , but these four other payments that were made illegally in erroneously are still sitting there pending on my account and they will not return my money
