Shocking service

Please note my elderly mother of 82 went to Dstv multi choice Umhlanga on Thursday last week Saw Asanda Per my insurance a new decoder was given on Thursday and the technician was to come Thursday afternoon or Friday. After my mother has hung on the phone today for hours We were told oh dear what’s the voucher number. We were not given a voucher therefore don’t have a number??? Zero help Call centre bounces you from pillar to post Account is in credit all the time and this is the zero service we get. I want a refund for the days my elderly mom has not been able to watch The fact a voucher was not given us not my mothers problem She took a taxi to Umhlanga to get this sorted 450 rands later for an eagle taxi !! We are being sent to pillar and post with no cooperation!!! Explorer decoder serial number A*** B O W Brock Her cell is *** I’m her daughter living in the uk Who pays her account in credit And my email is on all papers signed at the Umhlanga branch
