Don't respond/care/live up to promises

Contacted ADH on 29/03 regarding my S4 screen which needs to be repaired & spoke to Tshidi. As it is an S4 & there is no Samsung store in Potchefstroom, I agreed to pay the courier fees & asked her to send the banking details. I explained that my baby could be here in the next few weeks, I would appreciate it if we could at least just get the phone sent in ASAP. By Friday I had not received the banking details, so I phoned & explained everything once again to Simone. Simone advised me that they were doing a system upgrade & that they were experiencing some problems but she would ensure that I get the invoice before the end of the day. By Friday afternoon, I had received the invoice & paid it immediately & sent the proof of payment as requested. I heard nothing further & had to phone again on Tuesday. Again I got through to Simone, who said that the payment had only been received on Monday afternoon & that I should have gotten an email (Firstly, I am with FNB as well, so the payment would have been reflected immediately on Friday, & I have still not gotten an email) & the phone would be collected on Wednesday. Still not collected! I am now in early labour & fed up with this
