MtN no service

I am really very dissapointed with the MTN service. I KNOW we are all on Lockdown but you need to put things in place to help yoir customer.. On 30 March you blocked my accoint because of payment.. Firstly I pay my account every month in store and with the loackdown was not able to. I then on Monday paid the account online. But have been unable to getbthrough to the 135 helpline for 2 whole days.. O have sent mails lgged calls on the app... Logged calls online but account still not activated.. What must I do? Really upset with the service.. Dylan
