Megatrax/Deltatrax

Deltatrax/Megatrax from Wonderboom came out to do **** control, their initial quote was R1 p sq/m excl vat but on their final invoice it was R1.25 incl vat - that being the 1st problem. Their workers measured the area done - used length and width but didn't subtract my house area and paving as well as garage, I phoned Lawrence Meintjies(owner) and he updated the invoice amount using google maps. However I already made payment. He stated that he can pay the money(difference back) I have sent him a mail on 17/12/2021 and phoned as well as whatsapp, no response...Being owed R2000 Not happy at all with how the service rendered played out
