Horrible rain 5g service

Hi ordered the rain 5g router and SIM cards online it was delivered 5 days later , I tried to put it on it turns on and and no network, I called the consultant she said someone would call me back , it's been 2 weeks and 3 calls later I'm still waiting for it to be sorted but I've been debited already, 14 days and my issue has yet to be resolved ,very poor service I'm extremely disappointed with this level of service delivery
