Spar North DC doesn't pay for accommodation

Spar North DC booked accommodation for 2 persons on 13 June 2023. I had to pick up the customers and drop them off the following morning. The booking was done by Shoni Pandelani. After the customers were dropped of the next morning I emailed the invoice to Shoni. On 15 June I informed Shoni that no payment was done yet and he said he will do a follow up and update me. On 19 June I sent a message that invoice still not paid. No feedback from Shoni. 21st June I sent another message that the invoice is still not paid. On 22nd he responded that he made a follow up...awaiting response and if he can't get an answer by the following day he will escalate. On the 27th I sent a message again, he didn't even respond
