The worst service provider to sign up with

This is the worst service provider to sign up to....l signed up for web africa om the 20 th of march, 22 march R758 was deducted on my account for the router to be delivered and service to be active...well it was only until the 15th of April that my services where activated but suprisingly on the 8th of April R439 was deducted on my account l tried to ask what that money was for because my service where still unactive l didnt get an answer from the whatsapp agent then l asked her to log a request that the money be reversed only to be told that this was impossible so in less that a month webafrica had debitted more that a R1000 from my account when l had signed up for R549 promotion for 3 months, l then got an sms to say that my account will be debitted on the 27th again...so l went to the bank and reversed that R439...now on the 28th they went on to debit R891, they are telling me they are charging me for the debit order that was reversed...now my account is sitting on a minus because of webafrica who keeps wanting to debit my account for a service that only became active on the 16th of april....its bearly a month but the transactions l have received from webafrica are ridiculous, this company is a ****, their whatsapp agent are of no help at all, there landline number no one answers you will hold the line for over 30 minutes, the only thing they know best it is to keep deducting money from your account....l need this sorted out all these bank charges they caused they must pay for it
