Poor service delivery, Delays in rolling over to new tax period

I have tried to call the contact centre re rol***** which when I checked on Tuesday 3/3/26 advised I would be able to do so on 4/3/26. However the functionality was not available. Been waiting online for 45 minutes with no response. Then tried web chat and was told that this can only be done now of the 6/3/26. This being said so weekly staff shouldn't be paid this week due to lack of service delivery by a software provider. As a service provider to my clients I can't meet the required SLA's which then impacts me financially. I even requested a letter stating Sage delays but it could not be provided. I don't know maybe I need to use the other providers who update on time like Simple pay etc and who are much cheaper too
