Isaziso Selungelo Lomthetho
Le manuwali ihlinzeka ngolwazi nemininingwane ngemikhiqizo ye-Unicore Communication, Inc. (“Unicore”) okukhulunywe ngayo lapha.
Wonke amalungelo, isihloko nezithakazelo zalo mbhalo kanye nolwazi olufana nedatha, imiklamo, izakhiwo eziqukethwe kuleli bhukwana zigodliwe ngokugcwele, okuhlanganisa kodwa akukhawulelwe kumalungelo okushicilela, amalungelo obunikazi, izimpawu zokuthengisa namanye amalungelo obunikazi njengoba imithetho ebusayo efanelekile inganikeza, futhi lawo malungelo angase aguquke futhi agunyazwe, abhaliswe noma anikezwe kulo lonke ulwazi olushiwo ngenhla nanoma iyiphi ingxenye(i)ngxenye yalo nanoma iyiphi inhlanganisela yalezo zingxenye.
I-Unicore iphethe izimpawu zokuthengisa ze-UNICORECOMM” kanye nelinye igama lokuhweba, uphawu lokuhweba, isithonjana, ilogo, igama lomkhiqizo kanye/noma uphawu lwesevisi lwemikhiqizo ye-Unicore noma uchungechunge lomkhiqizo wabo okukhulunywe ngalo kule manuwali (sekukonke “Izimpawu Zokuhweba Ezingafani”).
Le manuwali nanoma iyiphi ingxenye yayo, angeke ithathwe njengokusho, ngokusobala, ngokushiwo, nge-estoppel nanoma yiluphi olunye uhlobo, ukunikeza noma ukudluliselwa kwamalungelo kanye/noma izithakazelo ze-Unicore (okuhlanganisa kodwa kungagcini nje kumalungelo ophawu lokuhweba ashiwo ngenhla), ngokuphelele noma ingxenye.
Umshwana wokuzihlangula
Ulwazi oluqukethwe kuleli bhukwana luhlinzekwe “njengoba lunjalo” futhi kukholakala ukuthi luyiqiniso futhi lulungile ngesikhathi lushicilelwa noma lubuyekezwa. Le manuwali ayimele, futhi kunoma yikuphi, ngeke kuthathwe njengezibopho noma iwaranti ngasohlangothini lwe-Unicore maqondana nokufaneleka kwenjongo/ukusetshenziswa okuthile, ukunemba, ukwethembeka kanye nokunemba kolwazi oluqukethwe lapha.
Ulwazi, olufana nokucaciswa komkhiqizo, izincazelo, izici kanye negayidi yomsebenzisi kuleli bhukwana, kungashintshwa yi-Unicore nganoma yisiphi isikhathi ngaphandle kwesaziso sangaphambili, okungenzeka kungahambisani ngokuphelele nolwazi olunjalo lomkhiqizo othile owuthengayo.
Uma uthenga umkhiqizo wethu futhi uhlangabezana nanoma yikuphi ukungqubuzana, sicela usithinte noma umsabalalisi wethu wasendaweni ogunyaziwe ukuze uthole inguqulo yakamuva yale manuwali kanye nanoma iyiphi i-addenda noma i-corrigenda.
