Bad service

Well I am very disappointed in Vodacom network and there service's is very poor I did pay my account up to date and now they claim they don't find the payment that I did make on the 30th May 2023 They claim that I never paid my account I had to go in to my bank just to look for the proof of payments and I did forward al the proof of payments to them via email just to find out there admin team does not keep them up to date so they keep on phoning me for the R1300 .00 I did pay in May 2023 and they cant find it on there system and did make a payment at the branch in Sasolburg.
