Do not buy online from MTN as they use DSV, a useless courier company

I Bought a SIM card contract on a Black Friday special with MTN online on 29th November. They said it would be delivered with 1-2 days. DSV the courier company they use is useless and they only tried to deliver on 11 December. The biometrics failed ( which the courier said often happens) and they had no backup proceedure, so the courier took the package away. Finally (after numerous calls and emails by me) on 19 Dec a manual delivery took place. However the SIM is still not active ( as of 31 Dec) as DSV seem to have lost the record of the delivery and have not passed on details to MTN to activate the SIM. MTN do not appear upset by this fiasco. My email complaint of 4 days has still not been responded to.
