Disgusted in Supersonic Service

I am totally disgusted with Supersonic and their service. I am sitting with a router for the past two months that is still not working. I had to make an upfront payment into their bank account before my router would be delivered. Delivery only occurred weeks later, and still almost two months later I am still without internet wifi. Several phone calls and whatsapp messages to Supersonic which cost me a hell of alot of money, promises made by Supersonic to send out a technician to rectify the problem never transpired, then they would send me a new simcard as according to them the simcard is faulty, that too did not transpire. No follow up or customer care from Supersonic. Absolutely disgusted in their service.
