Mweb service

Hi. I installed fibre in April through mweb. I don't know if iits vuma or Mitchell's fibre,although when i punch in the voucher i use the mitchells fibre portal.but buy it from the mweb site,but mu sms comes as vuma fibre. Yesterday was my last day of activation on the previous voucher. It goes off at 12am. I tried since 10pm to buy a new one. And this morning again.20/08/2020. From 6am till 9am. No luck. The site is not very user friendly. The link that they send me to purchase vouchers has expired. No reply on queries. The help line ask for details when u punch it in it accepts but when you want to confirm it ,it says you didn't confirm anything. Wasted R30 airtime with no results. Mweb please make it easier and more user friendly. It should not be difficult to buy a voucher.
