Two defaults on my credit file

Last year the Financial Ombudsman found in my favour as Lloyds bank sold a debt of £395 to Lowells in respect of a current account I thought I closed, however Lloyds kept the account open and applied bank charges.

I didn't know this until I received a demand from Lloyds for £395 I refused to pay this £395 as I switched banks a couple of years ago. After the Financial Ombudsman's decision, Lloyds sent me a letter of apology and compensated me financially and finally closed the account wiping this £395 of bank charges, they also stated that they would remove the 2 defaults from my credit file but this would take 60 days. I was looking for a mortgage and could not carry on with the mortgage as these defaults were on my credit file. That was in September 2016. I now reapplied for my Right to buy and wanted a mortgage so reapplied for my credit files and these 2 defaults haven't been removed. I've phoned the complaints dept of Lloyds twice and the complaints manager is always busy so won't talk to me. They've got my phone numbers but am still waiting for a reply and an explanation of why these 2 defaults are still on my credit file. I've only got a limited time before I run out of the Right to buy time as the council have given me 3 months and want a letter that I've got a mortgage offer. Many thanks for your advice which is much appreciated
