Poor service at MTN Trade route

I purchased an uncapped home wfi router and sim deal at MTN Trade Route on Saturday the 12th of August.

I experienced difficulty in getting internet access and returned it due to frustration caused by heir lack of competence to resolve the issue.

I requested that my order be cancelled and my money refunded.

MTN Trade Route have been unable to process my cancellation and refund for the last 6 days.

I want my order cancelled and money refunded.

Thanks
