Complain with the poor MTN retention services

I am writing this email to inform you about the serious concern with the MTN bad services. I called the customer service since last year June 2020 after upgrading my data & router contract for 081******x. MTN retention services they are NOT available at ALL to assist. When you phone them, the phone will ring for over an hour listening to their useless adverts with no one answering the call. This is really frustrating and it has given me the thoughts of reconsidering other cell phone network for future contracts when the current MTN contracts ends.

I took contract in June 2020 for data & router since even then, I have never received the router devices only DATA that was loaded on the sim card. I don’t know how will I use the sim card without the router and this has come into my attention by concluding to cancel the existing contract and MTN to refund the monies I have paid so far.

Please assist me I want nothing with MTN. It has come into my attention that MTN retention they don’t care about their customers and I wish this message can get to MTN management to fix this mess before it cost the company.

Please also investigate the migration of my cell phone network for 073******x. The company (they call from this number 06 ***) that was calling on the behalf of MTN has indicated that they won’t be any cost for that migration but I will be charger for prorata. Today, 12 October 2021 I just realize that my contract has changed only receiving data no SMS and no Minutes.

I do not know what should I do now. I will be invoice for something that I am not in agreement with....
