About

An independent du recharge online service

Fillstash is a small UAE team that turns a Du number and an amount into a quick, card-paid top-up. No app, no account, no upsell.

What Fillstash is

Fillstash is an online request form for Du prepaid top-ups, backed by card payment on a secure billing page. You enter the number and the amount, pay by card, and the balance is applied to that number. We serve customers across the UAE, with a registered office in Sharjah.

What Fillstash is not

We are not an app or a reseller of scratch cards, and we are not a payment processor — payment is handled on our secure billing page. And we are not a branch or affiliate of any network: we are an independent service that helps people top up their own numbers.

How we keep it simple

One form, a handful of preset amounts, and a clear price before you pay. We keep the field count low on purpose, so a du quick recharge stays a one-minute task rather than a form marathon.
