OpenSUSE Network :: Mount NAS But Only Have Read Only Permission

I am completely new to Linux and picking things up slowly. I have a question about mounting my NAS NV+. When I mount it, i use the following commands when logged on as user "matt":

sudo mount -t cifs -o rw,username=Matt,password=matt //192.168.2.15/Matts /home/matt/GRUMPY/Matts
sudo mount -t cifs -o rw,username=Matt,password=matt //192.168.2.15/Torrents /home/matt/GRUMPY/Torrents
sudo mount -t cifs -o rw,username=Matt,password=matt //192.168.2.15/Media /home/matt/GRUMPY/Media
sudo mount -t cifs -o rw,username=Matt,password=matt //192.168.2.15/Programs /home/matt/GRUMPY/Programs

GRUMPY is the name of my NAS by the way! It mounts properly, BUT i cannot delete or rename files, so basically the user "matt" has read only privileges, and root has ownership of the mount. How do I go about mounting these so that user "matt" has RW privileges?

When I log on as root user and mount them, I can read and write as required, so this has led me to believe that my problem lies in my permissions for matt when mounting them... I posted on the netgear forum and was asked to try and mount using the following command:
