Disgusting Service

They refused to cancel the contract even though the 30 days notice was sent. Claiming that MTN as the service provider is experiencing technical problems that is why I still can't get my prepaid number again till then they can't do anything about it. They cannot even confirm when will the issue will be resolved. However they credited my account with more data. Chantel said the given data is for free I'm not going to pay for it she refused to give me the call ref number because she knows that they ***** from people. Last year Dec I lost my phone, and it took they 3 weeks to do the sim swop for me. This is the worst poor disgusting services I have ever experienced.
