NO COMMUNICATION & CANNOT GET HOLD OF YOU

I have had my base installation done on friday the 1st Novemeber, the installation was done in a matter of minutes..the problem is has anyone tried to get hold of MWEB, i have tried all numbers for 1 week now with constant line busy. i dont believe that all your lines are busy, i have tried the following for the last couple of days with no success, 087 700 500, ***, ***, ***. all of these are constantly engaged. i have also tried the email support of which it give me an error that i cannot submit yet i followed all the prompts correctly. this is unacceptable. how do i contact you. i dont want to wait 14 days till you decided to send my router. also i need to provide MWEB with my vumatel code or number for my dispatch to happen...I CANNOT CONTACT YOU IN ANYWAY... this is really poor MWEB..
