I'm DONE fighting with this people.

I didn't think its possible to get worse service from a company than Lewis, but this people proved me wrong. For TWO months I've been struggling to have the payments "captured" on the system. I've paid and extra month's instalment just to get them to stop harassing me. And STILL no joy. I can't use the store card atm because of their incompetence and they literally HARASS me with phonecalls and sms. I need to take this further. Can I contact the ombudsman regarding this? I spend HOURS on the phone and on chat with people. I've send so many proof of payments that I stopped counting.
