Game gateway

i had gone to Game Gateway to pickup a TV that i had a rain check for, i had received an sms from game to come in and pickup my product . i went to the branch and spoke to Lopis Govender who in a very abrupt tone told me that there was no stock of the product and he could not check with head office or any other branch i should just cancel the rain check because i would not get the product . he also stated that Head office was not supposed to send me the sms because the stock that came in on the 22/12/2017 was sold in a few hours. i had gone to the branch on the 24/12/2017. i had also asked him to please confirm because we he made special arrangements to come and pickup the tv it was also a bit of an inconvenience if we had to leave and make another trip back. i feel this guy realy needs to go for some Customer Service training because he does not know how to deal with customers .
