Pathetic service from MTN

Signed up online for a mtn deal on 29th November 2020,I have been a mtn customer for many years. Since then have been trying to get a hold of someone to query my application as i had received no communication. Called call centers several times,wait for a consultant to assist me up to 20min on hold,no assistance received. I went into mtn store in cornubia for assistance however was told it was an online application and cannot assist,I need to call call centre. Eventually spoke to someone at call centre on 21 January and was told an email was escalated and I will receive feedback in 24hours,still no feedback. Non mtn customers I know have received their items for the same deal in a week,now how does that work? MTN provides pathetic service with staff who dont care and dont want to work and assist customers. MTN should not advertise offers they cannot provide to customers.
