Failed mobile order

Lost by FedEX. I opened a ticket with them. They closed it noting the time was lost. I just canceled my internet service and spent two hours getting a refund for a phone I never received. I do not understand why no one at Xfinity was able to confirm the phone/shipment was lost and send me a new phone before I had to spend 10 days trying to resolve the issue and speaking to seven different reps with three different tickets opened. I had enough and that is why I cancelled all of my services today less than a month after signing up. Xfintiy does not seem interested in retaining me. Worst customer service ever. All the reps were polite, but only the last one FINALLY resolved the issue by getting me a refund.
