Lenovo M10 part

On November 25, I ordered a part for a Lenovo M10. On the same page were two ads of the same part. One for R 15 bat from China, and one for R 395 and that one was local. ( PE and they had stock.) So, I chose local and paid the amount plus courier fees. Then it got silent. December 7 I made contact threw Hello Peter. Cable 5 phoned me and ask to remove the review as they will give attention to my order, in fact, its due to be dispatched. Then it got silent. December 23, I got 5 messages from Buffalo - China, with 3 different tracking numbers. On January 5, I made contact with Cable 5 asking for a refund, and the lady said it will take 5 working days, but on January 6 I received a parcel. Completely wrong part. I contacted Cable 5 again, informing them about the wrong part. On January 12 they asked for proof of the wrong part and on January 16, I sent it to Cable 5. On January 20 I asked again for the refund and also to arrange courier for the wrong part. They said that they will confirm with the courier and let me know. January 21, I contacted them again, but since then don't get any response. Still struggling to get my refund. Cable 5 is totally unreliable and never come back to me as client. I always had to initiate contact. I kept proof of all correspondence on e mail and whatsApp.
