Pathetic service

I purchased a 28 day vuma voucher on Thursday from mweb and after i purchased my internet services was still oof.i contacted mweb spoke to technical person and he said mybe vuma didnt receive payment yet on their side he i explained thag the los red light is flashing he put me threw to another person and then call went office.i called back again to mweb waited in line and spoke to a sales person explained same story and the lady told me of the red light flashing its a cable connection problem she will log a a call with vuma and vuma will have to come out.today i tried contacting mweb and waitsd so long until eventually i ran out of airtime again i bought time tried once more and still waited long then i tried contact vuma via the messenger app still nothing. Think is unacceptable because i purchased my voucher on Thursday and have proof of payment but no internet service im losing out on this service so what going to happening to my 28 days?
