Webafrica the worst internet contract provider

A month ago I lost my bank card,so I blocked it,after 2 weeks I got another card after much hassle bcz of lockdown. Then I received message about payment not going off,so ever since I've been trying to get hold of webafrica on their number that's on their website to give them new card details cz of new card in order for payment to go off. I have spent every day 3-5 times holding on for more than 10min at a time waiting for someone to answer. Then finally automated gives you option of a call back option 1 blah blah. Nobody calls you back,then I thought let me try a different option wether sales,it support etc. Just to give new card details but you will hang on till they kingdom come. By now I'm ****ed off as I spend more than a R100 airtime trying to pay these ppl. A week ago I sent them emails with new card info for payment,nobody answered any of my mails,nor any payment went off. Two days ago my internet service was suspended. Again I'm trying to contract them now on sales,IT support etc.and then someone finally picked up an promised to call back but didn't. My question to this unprofessional workers is why must I suffer trying my utmost to pay them yet they still have the audacity to suspend the internet service. This is but only the second month I'm with them but after this I should just take my business elsewhere.
