No after sales service

I had an account for over a 18 months ago which was closed. I used the account purchase my glasses from spec savers. When I wanted to used the account again I was asked for all the documents and I ha not missed a payment with them I paid the account in full I have a settlement letter this account still shows on compuscan, experien and trans union they still HAVE NOT REMOVED THIS WHY. Beware of this company. They quick to give you an account and take your money but won't assist once account is paid up.
