Bad service.

I took out the unlimited wifi with supersonic R399. It was established last month that my area does not support the FTLE, The router and the Sim were collected on the 7th of June, I was advised I will be credited after 21 working days, I called to do a follow up I was told the cancelation is not loaded they escalating. I called again and I was told cancelation not loaded it will take another 21 working days. Supersonic offers the most horrible service ever they should close down.
