poor service delivery and false information

I am so disappointed in Italk and MTN, i paid for a new contract/month to month on the 17th and i was told that they will deliver within 2-3 day but i still have not received anything. i was was told that i need to follow up with DSV and they told me they only deliver on monday the 2bd of march. I made a payment for the February and March but how can i receive a router in march when paid for Feb aswell. Ref ***
