Ask the supplier whether the old quote remains valid before paying. Preserve the original package and conditions in the request so the supplier can identify what needs to be reconfirmed instead of treating the price as permanently available.
Identify the original offer
Send the quote reference or date and the credit quantity. Include any stated validity period. If the quote included an exception or special condition, mention it explicitly rather than assuming a new support agent will infer it from the amount alone.
Reconfirm the complete terms
Price is not the only detail that may need confirmation. Ask about consumption rules, permissions, validity and the current payment instructions. A familiar amount does not establish that the rest of the arrangement is unchanged or that a previously used payment destination remains appropriate.
Save the updated agreement
Keep the new confirmation with the order and label the older quote as historical. Use the current terms for customer promises and internal calculations. Avoid presenting a previous quote as a public fixed price for 8K IPTV packages that are offered on request.
