Bad experience

I have had my simcard lock for the past two months for no reason. When I try to make a call it says "your card had been locked please call customer care" their customer care forces you to use whatsapp self service which has limited options. I can only receive calls but I can not make any, I can't recharge nor check airtime. The customer care is completely useless. Now they keep telling me that my simcard has been inactive for x number of days and I should recharge to avoid suspension. Remember, my card is locked, right? Now how under God's blue heaven am I suppose to recharge?

My number is ***

For 5 years I have been using this number I've never had any problem but now...
