Where is the money

Wow, I am quite shocked by lack of communication from Stanlib, on the 22nd February I helped my wife place an investment in your Tax Free investment scheme, since then not a word, no acknowledgement of receipt, besides an email requesting proof of payment which was submitted with application at the start. Eventually on 3 March she received a confirmation of receipt sms, however, the investment is not linked to her portfolio in your books (despite this having been requested telephonically on two occasions), so, is it invested?? We have no details or account no and are unable to check investment on the net. Further and of more concern, not one of our emails, 22, 24, 26, 27 February and 2nd March have been responded to. Whilst I accept that you probably regard us as just some nuisance clients. I do however again request that the new investment, if it has eventually been invested as requested be properly reflected in her portfolio. Look forward to some better service or if our investments are not worth your attention, let us know and we can go elsewhere. Look forward to some response.
