Service not rendered and our calls are declined

Goodmorning

We made an order of Tshirts while training at the military base in Kimberly at 3 sal and the lady who was coordinating is Karen who works for Cmt clothing Bee.

We ordered Tshirts as a bulk and paid the invoice and she promised to deliver in two weeks however two months passed and arrived the 2nd last day before leaving Kimberly,only to deliver rejected quality with kids sizes.

We then asked she fixes the sizes and she assured us in a week she will be done and courier them till date our Tshirts aren't delivered.

I can confirm that training is over and we still have not received our Tshirt and worse we are back in Gauteng its 3 months since we put an order

Karen has been communicating with Mario who is our colleague but she eventually stopped responding and declines his calls.

Can we please be refunded .

We have invoices and communication to prove.
