Business data sim cards after 2 weeks order incomp

Ordered 3 x data sim cards with tablet as per their offer. All documents sent - then told documents incorrect. New docs completed and forwarded. Were told all now OK received Approved sms on Tuesday 7 April on Tuesday 14 April sms pending. After numerous calls told order would be delivered Friday. Today get told that now they cannot complete because bank statements NOT stamped by bank. What kind of service. I have 3 x salesmen that cannot use their tablets to go and see customers. Really I have spent hours trying to sort this out and now this. I cannot get a manager to call me or the issue sorted being given the run around. Original lady (Claudene) wonderful and quite frankly tried her best. She is dependent on other departments and then mail this afternoon about the bank statement issue! This is just not customer service. We are an international business and trying to get service from whom we believed to be a good service provider! Really?!?!?!?!?
