Extremely BAD Customer Services

This is one of the worst companies I've dealt with thus far, a payment was made two weeks back the 6th March however there was no data added on both sim cards namely NH NW PL, NH NW PY up to date, since then me and my wife have been phoning timorously, I would even hold on the line for 30 minutes and my wife for 20 minutes max and all you hear is just is a song playing on the background, we even tried emailing several times and no one got back to us.
