No LTE connection since 22 December

I ordered LTE 16Dec, recieved my sim on 22 Dec and was prommised connection within 48 hours. It is now the 06 of January and no connection. Everyday I am passed from one department to the other on the useless chat service and told “ *Arezona P.*: Please accept my apologies for the delay in response as we have been experiencing a high-chat volume which has made it difficult for us to attend to all customers queries accordingly.We would like to assure you that this is not the level of service that we are accustomed too and therefore would like to thank you for your patience, but stay online and we will attend to you”

I am tired of apologies now and nothing being done to activate my LTE
