Hi @Sohrab, I'm here to help! I inform you that at the time of renewal we will in any case deduct the cost of the offer from your residual credit, which will therefore go negative, but we will not deduct other renewals. The month of validity of your offer begins when the remaining credit becomes positive, so you don't waste a day. Below is the link with all the info: https://supporto.ho-mobile.it/t5/Soluzioni-per-passare-a-ho/Tutto-sull-offer-ho/ta-p/126 I remain at your disposal for any further clarification.
