In the beginning of this year, i had a deal with a guy from china who buys used and new phones from US and EUROPE from locked carriers like AT&T then he unlocks, refurbishes and sells them. So I'd buy his handsets which were very cheap e.g I'd sell a SAMSUNG GALAXY NOTE 4 for ksh. 50,000 at a 95% profit.... So i obviously sold out, but these two clients(they work together) bought HTC BUTTERFLY S @KSH.28,000 ... Their phones auto updated and now they are locked (unusable)... I've taken to all fundi's lakini they are not fixable... The only way is to replace a chip called EEPROM... Now they(CLIENTS) want THEIR money back or they involve the cops..... (am not refunding their money coz when they paid, the phones were working).... Should i go to the COPS and report them first before they do?
