Cannot Pickup 4G/LTE

<p>Hi there </p> <p>for some strange reason I just cannot pick up LTE on my phone. I have a LTE enabled device, I am within an LTE coverage area. This is the second time this is happening to me. At first my number was on prepaid, then it got moved to contract, I wasn't picking up LTE, I had to do a sim swap for me to pick up LTE, now my number is on prepaid again, I am once again not picking up LTE. I cannot keep doing sum swaps just to pick up LTE. I have called the customer care with little assistance provided. I now cannot call the customer care as I have reached my monthly limit for calling VODACOM's customer care. Like it's my fault that Vodacom cannot help me. How do I now get any assistance? I have seriously had it with Vodacom. I am now this close to porting my number to another network. </p>
