PASOP!! The Courier Guy had a 100+% Price increase on large parcels!!!

The Courier Guy had a price increase the 1st of November. I have a small business, making toys and I have used them to collect my bales of ball fiber from JHB and deliver in Pongola. At the end of May 2024, I paid R762 for a bale of 23.1kg. On 19 November 2024, I had to pay R1625 for a bale of 21kg. This is a 100%+ increase from last time. I have contacted them with no luck at all. They say this is the price on their system and they cannot do anything. This increase means that I basically have to double my prices, which will kill my business.
