Credit Request

I recently bought Huawei 5G All-Scenario CPE/Router I've been having issues with connectivity,no internet,checked all cables, power flashing green. Escalated the matter via email,phone calls,through social platforms. I'm utterly disgusted by the appalling service received. I then got through and was assisted by Yasin (***) he advised me that I don't have coverage in my area, I asked how because before one can receive CEP as per their website I have to check first if I do have which it indicate that I do hence the approved of the CEP. I requested for a credit because I was debited for a device that doesn't work in my area. He said he will escalate and cancelled the order as of yet haven't received feedback on this query. Surely turnaround time doesn't take more than 72hrs without updating client? I need that credit due to me to be processed today.
