不誠實的Netvigator

因為Netvigator的合約已完,所以有sales call我,她說可以用舊價($195)續約,我說我有$90和記(固網电話+寬頻),她就說可以$165 upgrade 到200M光纖!我说要考慮。 幾天後她再來电,但她說 upgrade 要$230 但長期客戶可以減至$195,我以為記錯是$165 for 200M,所以同意安裝. 作天裝了,發現只去到19M,同時發現$90和記可到90M, 所以問那個sales,她說你要的是30M,題意我找CS,我以為我又記錯. 再問CS,她說可以$230/mon給我200M. 之後到街上netvigator shop 發現我的大厦有$165 200M !...
