Complaint: Casseldale Spar - Springs

Since 28 December have been trying to get hold of Spar Head Office to bring my complaint to their attention and just get an automatic reply saying will be contacted within 3 days. It has now been over 13 days to receive a reply. This is disturbing as my initial complaint was about bad attitude received from the said teller / management and it seems this bad attitude of not trying to assist customers is being shown by staff at head office as well so it doesn't surprise me that at store level, management and tellers treat regular customers with such bad attitude and disrespect the way they do! My original e-mail was sent to Thola Mdlusi at their Customer Care and since then I have received no response just a generic will "investigate and get back to you within 3 days". I have also trying phoning the landline number at the office but there is no answer and just a message service is available.
