Sage trying to push away clients?

We have recently upgraded to Sage50 from Partner V14. Our Sagepay/Netcash Cashbook has become difficult/near impossible to update with the new upgrade. After numerous struggles with contacting Sage support (incl. being cut-off more than 5 times by staff), we were informed there is no simple solution yet and they tried to show us how to import the Netcash statements through their generic Bank Manager csv. import function. Also the download file from Netcash has to first be manipulated extensively for this import. This is just not on!!!! We move to Sagepay (now Netcash) for the simplicity of posting the cashbook. Sage is now making this a huge mess due to their poor software development. I have even started contemplating a move to Quickbooks or any other alternative that is more client friendly.
