3G/2G Network blocked on my line

This is my 2nd report regarding my sim card problem. My 1st complaint was on the 6th of August and haven't recieved any help from Cell C. Selwyn, the technician who assisted me at the customer walk in centre said my phone 3G/2G network was not active on my sim card, activated to use LTE only. He tested my sim card on different phones and it only worked with LTE network enabled phoned. It's surprising that all of a sudden my sim card doesn't work with 3G/2G network when it has been working all the time. My verdict regarding this problem: 1. My sim card has been deliberately blocked by Cell C not to use 2G/3G network. 2 I am due for upgrade, hence blocking my sim card to force me to upgradae to a more expensive phone which runs LTE network. 3 Cell C has been bombarding me with sms and phone calls to upgrade my phone hence blocking my line. I am giving Cell C 2 weeks to unblock or activate 2G/3G on my sim card. If not I am going to cancel my debit order, demand that my contract be terminated, get all my familes to cancel their Cell C subscriptions and start a campaign against this *****elent and ******* ways of forcing customers to upgrade. I will get the media to assist in this.
