Pathetic service re an existing non payment of entitled uif benefit claim

Since leaving work last year I have not received one single benefit payment. Online application was submitted and approved but no payment - there are multiples of telephone calls to call centre and emails but to date no resolution. I was requested to resubmit the application in January and after numerous follow ups was advised on sms and email that application approved and payout would be end February - but to date no payment received! Very frustrating as there are no responses to my emails and it's pointless contacting the call centre as all they advise is they will escalate query. But still no response as to why I have not been paid - by now I should be on my end claim benefit term - but instead am in the dark. Nothing has changed in my initial application ie bank account, address etc - all is the same. There is no means of contacting the Paymaster as advised there is no direct telephone or email. It is coming across to me now as being fobbed off hoping I will go away! How will I ever get to receive what I am righfully entitled to - after paying to UIF since their inception! It is pathetic to say the least and leaving me no option but to take the legal route as I have the paperwork to back up a case they will pay for.
