No service -FIBRE.

I am a mweb customer. On 16 March 2018 I received the confirmation sms that my MWEB fibre order has been processed and that an order number was received. End of March 2018 Open Serve came to install the fibre line. The following week I contacted Mweb to send me my rooter (05 April 2018) and was received a day later. I phoned back to activate / connect the fibre line. The first two days I made a total of 9 phone calls to Mweb, only then they were able to tell me that the B number does not match / correspondent with them and that I app**** with a different provider. I have told them countless times that I am a MWEB customer and that I have only app**** with them. They then told me that I will receive a phone call back as they have escalated the matter to the relevant department, to see how they can resolve this. Another week has passed and I had to phone MWEB again this morning for answers. I was provided with the wrong B number, which is not my problem - I am a paying customer and now have to phone how many times a day trying to get assistance. Till date nobody has contacted me, tried to resolve this matter.
