Still can not buy data

Unfortunately I have to repeat my complaint as it still has not been sorted out I can not buy data using ussd or the app, says my msisdn number has been deactivated I have been asking for the past two months for this to be sorted out but it has not. I was contacted last week and told it would be sorted out by Monday well it's Wednesday now still not sorted, the consultant told me that due to system upgrades some people's profiles were changed but they are aware of it guess not cos I still can't buy data. Makes a lot of business sense for a company to prevent clients from purchasing their products. So frustrating
