Bad customer service

had a query that had to be resolved by Capitec Forensic, went to the Kuilsriver Branch four(4) times and i have been told that 'Mpho' is not available, apparently he is the only person who can assist me.. in all the 300 and something branches of Capitec in South Africa is it possible that they only relying on one person to help them?? IVE NEVER EXPERIENCE SUCH BAD SERVICE IN MY LIFE. Query not solved even today.,The lady i was transferred to on the 21 September 2015 hung up the call and did not apologise when calling her back.
