unhappy new mweb customer

*** i am afraid that ive made a mistake chosing mweb as my new service provider. i signed up on the 1st of Feb. ive been calling them weekly to find out if im going to have internet from the 1st of march to no avail. the calls keep on being disconnected and no one ever bothers to call me back. ive left my number several times but no one makes contact. so right now i dont know if im going to have an internet connection in the new month as no sim card nor router has been delivered or arranged. if this is how their service are going to be going forward, id rather not be a customer and find someone who are on top of their customer service calls.
