Dont sign up for any contracts

Called me for a contract Saturday, Got approved and they wanted R250 to proceed, Monday Im struggling with them and already sent everything through on Sunday, Monday they request the details again, Tuesday morning they say all is good they will deliver Wednesday, Wednesday morning I get a message after paying after submitting documents back and forth, it was declined because my signature is different as what it was on my ID - 3 years ago!!! You got to be f kidding me. I'm still waiting for my refund - you can't ask money after approval and then just decline it - Istore is just as bad as MTN as they go through them. You guys can shut your doors to be honest, I have never in my life experience such bad services between you and MTN the last month!! You have my banking details, Im waiting for my refund, Im not gonne pay for companies that promise me stuff and then cancel it after it has been approved
