No feedback after requesting to come and inspect TV

This is honestly the worst service ive received from your department and the actual n1 city incredible connection store I've been sent from pillar to post from hifi to incredible both telling me different information about the TV and warranty a guy named Mellcom then calls me and I explain the situation once again to him and he tells me to email him the proof of purchase which I did but the email address returns and the number he provided me with cannot also receive calls as with all your numbers found on Google. I then personally went to the shop to go and have then copy the receipt and this was last week I am still waiting for someone to come and inspect the tv so that I can get a refund as it is not working only when I went to the store they informed me the device is not google certified but when I purchased they failed to mention this as it was clearly about the sale this is really unprofessional and I need someone to come and check the tv out and fetch it as it is too big to fit into my car please have someone call me or escalate this to your manager please!
