Terrible Service!!

My local post office failed to notify me of a parcel that should have been collected. I only received the 1st notification slip after they returned the parcel. I'm desperately trying to intercept it before it is returned to the UK. I've been trying for 3 hours to get through to Jhb Intl, but they NEVER answer the phone. My local branch did not try and rectify the problem, instead they made their mistake my problem. Tracking: RI***ZA
