Can't receive calls and sms's

NO RESPONSE!<br> <br> I have been struggling since last year August when I signed a contract with Altech Autopage. When some people phone me the operator says my number is incorrect or it doesn't exist, i don't ever receive sms's from people! I have been to Altech and then to Vodacom and no one is helping. i have reset my phone, wasted my money by doing a sim swap and no one can help me! MTN numbers dont get through to me, some Vodacom numbers do, and then some landlines also dont come through!<br> <br> I refuse to pay my contract if it doesn't work properly - you are delivering half a service so I don't understand why I should pay R200 a month!!! <br> <br> Please contact me on *** after 16:45 or email me if you cant get hold of me on my number (the one that isn't allowing some calls to come through! <br>
