Supersonic LTE Exsessive Price

Deeply disapointed with Supersonic. I have been a FLTE customer since Oct 2019 paying R868 per month on a sim only deal (Purchased my router upfront from Supersonic). This is a month to month deal for 300Gigs. The same deal is currently running (without any promo) at R799 per month with a free router. Disappointing that Supersonic's long time loyal customers get a worse deal than new customers. In other words if I cancel my current contract and take out a new one, I save R68 per month and get a free LTE router. Surely this cannot make sense and is not fair to long term loyal customers. To be clear, this is not a contract, it is a month to month arrangement. I have logged a case for this to be reviewed as.
