Worse customer service I've ever encountered

I've always maintained my John Lewis partnership card account faultlessly for 2 years then I missed a payment as I couldn't
Log onto my account from abroad, My fault I missed my first payment by a couple of days.
Problem is they suspended my online banking account stating phone customer services, you first have to Imput
Your card number and then they just don't answer the phone I've tried and tried for hours on end its as if it's on a loop.
Frustrated I phoned the stolen cardline got through to someone and they said they won't talk to me as I'm in default and
Have to speak to the collections department ( the department that won't answer the phone )
I could understand if I was a bad customer but it was my first slip up, In the end I did a balance transfer from another card as it was the only way I could make a payment.
There are much better cards on the market with good customer service, I will be adding HSBC to my never touch again list.
