Rain is not worth it

Could you kindly advise me what to do. It's 48 hours now and I have paid for a service I can't use because no one from Rain is assisting me. Should I rather cancel my contract with you for A FULL REFUND and expose you guys for your appalling service on all media platforms or is SOMEONE GOING TO HELP ME?????? I sent this to Rain 7 days ago and still no response from them. Theres no contact number where we can be assisted and their service is the worst I have ever come across.
