Frustrated Customer

I was ****** and phoned iSmart(PTY)ltd Telecommunications service provider in Cape Town, South Africa on the 29th of January 2018 to block and order a new sim card for me. Today is the 19th of February 2018 and I am still waiting for my flippen sim card. Every week when I phone they tell me there is a delay from the supplier`s side, the one day when I phoned the lady told me the sim card is with the courier, I got so happy than 2 days after that the guy told me no there is a delay with the the provider. I am so bladdy ****ed with them all I want is my flippen number. This so frustrating I can`t even use internet banking without my flippen number because everything is linked to that number. My contract end June 2018 and I will not use them again because this is the second time this is happening and no one from iSmart even call me. This is pathetic customer service and unacceptable behaviour.
