Money debited no phone and no answers

Good day I would like to complain about TELKOM MOBILE'S horrible service. I have been a longstanding client with them. On Thursday the 26th of April 2018 I ordered a cellphone online. I spoke to Zama and was promised hand and mouth after the debit is received it takes 3 to 4 working days for my phone to be delivered by courier. My account has been debited on 2nd May 2018. I have called begged and pleaded. But have been sent from pillar to post. Now eventually after 8 working days NOTHING. Now I am frustrated and I want to cancel the contract and have my money back but everyone I speak to gives me a number that no one picks up on. I want people to not make the same mistake as me rather go in to a shop than to be messed around by TELKOM like this. No one can answer me as to where my phone is and the tracking number I was sent do not exist. Nice telkom.
