Absolutely shocking service!

I have no idea how Supersonic is still in business. We call in every single day (5 days in a row), sometimes 3 days we well, the voices on the other side of the phone are calm but uninterested, we request for managers to call us back, they still have not. 2nd month in a row that we cannot top up, we have been down for 6 days now, each sales consultant gives us a different story, no call back, no apology, no technical explanation. Is this even legal for an entity to operate like this?
