I received an invoice with no details about the amount. It turns out that it is the bill linked to my ex-employer because months after, my employer has still not terminated my account. 1. if it is employer's bill, send it to them, why sent to me2. why no details on invoice3. why no resolution in writing but excepting verbally only that it is a technical fault 4. why no resultion, why should i ask my ex-employer for refundThis is totally a fraud and unprofessionalism both on proximus and ex-employer's end. Not only I want a refund, but explanation in writing that why they sent a bill to me with rough language that I must pay them, when there are so many issues on their end as explained.
