Terrible and Fowl play (pricing and costing)

On the 02/11/2025 I was issued quote by Peter Ramathoka which was on PCC Mmola Project which is not my company. I never read much to it but was wondering if a backroom plumbing can cost us so much. My building project was only to be in December, on the 22 I came to make a purchase and upon arrival discovered the quote was left home. I then asked Peter to check for it in my name, and he said there is none I called home to get a screenshot and whilst waiting the plumber to do installation was in the store. Peter was agitated and unfriendly with a raised tone. I requested him to make the quote in my details as I am paying for the material to be bought. He told me that it's going to cost me more. That made me wonder why because that was the same material. I requested him to do it as in me I knew had another hardware quote. He made the quote, and it was R1400.00 more as compared the previous made in the plumbers account 02/11/2025 which was R7590.56. I asked to pay as I pay using their speed point it declined R8126.74 processed via my cheque card. I tried on my credit card and then declined the transaction. I received two notification that both transactions went through both my accounts successfully Peter then said Oh! We just received message our speed points are not working. I called my banker whilst waiting by the till and my bank confirmed the transaction were successful and must ask plumb link to reverse on their speed point, but Peter continued to tell me I must wait for Reversal which to date never happened. He further advised me that his manager instructs I must not be issued material until machine is functional. I requested that all be cancelled so I go buy at another hardware then I was told I can then receive material and come back to pay. The amount taken from my account is R16252.00 double what is bought and to date my R8126. 00 is not refunded, the material is more than the 1 room with 2wall hang toilet 2 basin. The purchase invoice has items with product number cut. My suspicion is FAULTY play between my plumber and Peter which I believe is *****.
