PATHETIC CUSTOMER SERVICE!

Since the beggining of March,2021,l have been calling the Call Centre several times to get clarity as to when will l get my refund.l have emailed all the requested documents but my refund is not yet paid/ Another Agent by the name Sipho Mogolegang,emailed me saying my refund has been processed and l will get my money within 3 working days and today l phoned the Call Centre again and spoke to Agent Denker who told me a totally different story,she said my refund has not yet been processed coz my details are not corresponding to what l emailed them; this doesn't make sense to me . Can someone senior help resolve my refund query as l'm really sick and tired of being sent from Pillar to Post. You can call me on my work number ***.
