Blue tier con by Samsung

I purchased my entire homes appliances under the blue tier special. I registered to receive my pin in January in order to redeem my hotel stay for 2 of my vouchers .I wanted to use it in June 2020. Due to lockdown the hotels were closed indefinitely and I did try to make contact during lockdown to the blue tier line.There was no answer quite a few times. When I contacted them today, the call centre agent said that it has expired as it was valid for a year only. The flight vouchers were extended but not the accommodation vouchers. How were we supposed to book accommodation when there was instability during lockdown and travel was not permitted .Almost every other facility has extended on the basis of covid but blue tier does not want to provide any assistance with regards to this. They refuse to allow me speak to a senior team member . It's unfair to NOT extend this as we were in a pandemic...so blue tier cashed in on this through the blue tier **** that Samsung seems to be running. I contacted Samsung and their agent said that she has not received training to handle this query. I am extremely disappointed at the **** that Samsung is running. We buy appliances under this premise but there is no reward. It's a con job. I am still at square one and no one can assist
