Very bad service

I have a cell C prepaid number that I was using only on WhatsApp, so I decided to do a sim swop before the number is deactivated on the network, 1st I call cell C to check if the number is still active on the net, of which I was told it's still active so I go buy a Sim card then I call customer service, now they can't do a Sim swop I must go to the shop, I drive 20kilos to the shop, then when I am at the shop they to can't do a sim swop, Then I try calling customer service n my number does not go through but keep looping on the automated services everytime I select 9 to speak to the agent, I call using a different number but use the number in question on the enquiry still it does not take me to the agent, then I call using a different network then it goes through, so cellc discriminate against my number going through to the agent, both my cell C number where blocked from speaking to the agent how childish is this, Secondly why no one can help me do a sim swop I dont know, n that ************** number 2, cos no one knows why I cant do a sim swop even at the store that they told me to go to how unfair that I had to drive 20 kilos for no help at all, yes I agree the number hasn't been active on the network for some time now but if it hasn't been allocated to anyone why can't I do a swop.

Very very very bad services
