Worst service provider

Extremely dissapointed with the pathetic service from Vodacom. Ordered my fibre line through Vodacom which Vumatel technicians installed last Wednesday. Line was installed within an hour but to date I still have no wifi. Everybody at the call centre gives me a different explanation. I've mailed them two days ago but still have no response. Yet they have the audacity to debit my account today without any service provided.
