BAD SERVICE AT SUPERSONIC

I have been getting poor service from Supersonic since I signed up with them over a month ago. From The Router having a bug and having to reset every other day, to them cutting my internet even though there is data, to my calls being dropped when I call the call centre and no response on WhatsApp Line.And also being charged for extra data even though I make the top up from my cheque card! I am working from home and missing important meetings because no one gets back to you as promised. I am appalled at their service and will never recommend to anyone.
