Camella Homes Tanza review: Demand letter to vacate

We've been paying for almost 6 years now, from the date of down payment until now (including lapses). Because of pandemic COVID19 we started having hard time paying our monthly amortization since my hubby is a seaman. We're constantly talking to our bank officer. Until today Feb 19 2022 we received a demand letter to vacate from law office of Camella. It shocked us because we've been talking to RCBC bank where we got our housing loan. They have asked if we even paid at least a month in the year of 2021, and I said yes! Then RCBC told us to email the receipt of 2021. After that we also talked to collection dept of Camella who's handling our account about that and even ask to update us about that. Then suddenly we will receive this demand letter? Considering the crisis that we have? We're already planning to start paying again in Feb 2022 and plan on asking the bank if we can pay the lapses in staggered for a year or two. We only need to know if we can still be considered to pay under bank because if the property will be in in-house financing we cannot afford it already. We would just like to ask for consideration and payment reconstruction. Thanks and hope to hear the soonest time for our concern because it really affects us and gives us stress.
