So much for service

Over a month ago I logged a conplaint on the TASTIC WEBSITE regarding mites that were in 2 packs of 2kg Tastic rice that were sealed and to date no response was received. So I decide to call to log the complaint telephonically as maybe I would get help from there but was I surprised as firstly, the call kept getting disconnected after 5 tries, I ask the lady who answered if there is any customer service department as I am now furious and would like to complain but I haven't gone through to the department who is supposed to take my query but then to top it all off the receptionists starts shouting at me, telling me I must just try again and be patient because they cannot do anything at the moment and when I asked her not to shout she hung up... what is this? A circus? I am deeply disappointed as I just tried to log a complaint that could help them in future.
