(7)To ensure a prompt handling of complaints, crypto-asset service providers should communicate decisions on complaints to the complainant without undue delay within the timeframe determined by the crypto asset service provider in the complaints-handling procedure. This timefrome should not exceed 2 months from the date the complaint was received by the crypto-asset service provider. Only in exceptional circumstances where the crypto-asset service provider is not able to meet that timeframe, the complainant should be informed of the reasons for the delay and of the expected date by which a decision will be delivered.
