MTN Prepaid Airtime Dissapearing

I bought a new sim card recently from PnP. The sim card was RICA and i loaded prepaid airtime. Shortly after recharging the airtime disappears. This keeps happening over and over again. I suspect that this number that i got was a recycled number. I checked if there are any content services subscribed and there are none. My data is always off and still the airtime dissapears into the ether. After numerous attempts of trying to contact a call center agent i finally logged a call (Ref #: 1- ********** 0596) on the 05 October at 16.50pm. I was told that MTN experiencing some issues and that my query would be resolved. Almost 10 days later and nothing. I recharged with a R10 voucher recently and the same things is happening. I have 5 MTN contracts and 1 prepaid number and i am appauled how prepaid customers are being treated. I'm hoping that someone from MTN reads this review and looks into my case. MTN has been my network for years but im thinking of trying on of the other prepaid providers.
