This is my worst experience ever - they do not honour their offers and ignore complaints. BEWARE of JDWILLIAMS!
Their own offers are not recognised by their "system" although clearly visible to call centre, who placed "notes" on my account to acknowledge the offer I bought. I paid in full what I owed but 8 months later, after multiple premium phone calls (at my cost) and 2 complaint emails to their customer services (never responded to) and an official complaint raised via RESOLVER (Money Saving Expert Tool), which was also ignored for 32 days thus far, my account still shows that incorrect offer-balance to pay, my previously unscathed credit score is seriously affected and I'm getting debt collection letters from JDWILLIAMS.
They just ignore complaints and they do not react to "notes" made on your account. I will NEVER buy from them nor sister companies Marisota, Simplybe etc again.
I am currently escalating to the Financial Ombudsman.
Please be very aware of this scandalous company!
