I bought a Huawei phone at the Vodashop Trade route Mall Lenasia in August 2015 by around December 2015 the phone had software issues , i took it back to the Vodashop and they sent it in for repairs .I got it back in February 2016 , That phone packed in with the same issue i went back to the Vodashop beginning March 2016 and was advised it will go for repairs again . I then told them that i do not want that phone as it is clearly a problem i want to exchange it for another brand . The manager then told his agent tell me to call repairs and sort it out with them , so i logged a query on the Vodacom website and Divan from ARC told me to booked the phone in to ARC and he will process a refund , at some point in the 6 weeks i was waiting Divan stopped replying to my emails and i was being ignored , i went back to the store and the manager once again told his agent to tell me i must call repairs and sort it out with them , This was unacceptable , i had to force someone in the store to help me , and still no help , the store told me to just keep emailing Divan and they want to give me the same brand of phone knowing the problems it has .i do not want that brand of phone .
